The primary objective of this study is to explore the mixed convective heat and mass transfer in the boundary layer of Casson nanofluid flow. This flow passes through an upright dish and is subjected to an externally applied magnetic field and thermal radiation. To analyze this, suitable non-dimensional variables transform the time-dependent governing equations. The dimensionless equations are numerically solved using the explicit finite difference method. The solution convergence is ensured properly by thoroughly checking comprehensive stability and convergence criteria. This research provides detailed profiles that showcase the velocity, temperature, concentration, and isothermal distribution, along with patterns of streamlines and unique features of various flow, thermal, and concentration fields. Through a linear evaluation of the radiative heat flux, it is convincingly shown that the Lorentz force significantly influences flow profiles, ultimately leading to their reduction. The numerical results indicate that the velocity significantly increases by approximately 70.56% in the free convection area. There is a substantial increase in friction by 17.89%, demonstrating excellent flow resistance. The thermal performance also improves, showing an approximate enhancement of 12.98%, suggesting a higher heat transfer efficiency. Three new linear regression equations for multiple variables are derived. It explores the use of thermal radiation in Casson nanofluid flow over a flat plate affected by MHD, resulting in enhanced heat transfer and improved flat plate cooling.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"263 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Glass fiber-reinforced composite materials filled with B4C and Gr at different weight ratios (5%, 10%, and 15%) were manufactured using hand lay-up method. The produced composite materials underwent various tests, including mechanical tests (tensile and flexural tests), tribological tests (wear behavior), and drilling tests under different parameters. Additionally, SEM images of the worn and fractured surfaces were examined. The addition of both B4C and Gr fillers adversely affected the mechanical properties of glass fiber-reinforced composites. It was observed that tensile and flexural strengths decreased with increasing filler ratios. However, the addition of B4C and Gr fillers enhanced the wear resistance of glass fiber-reinforced composites. It was revealed that in drilling operations, as the feed rate increased, the thrust forces increased, while the cutting speed increased, the thrust forces decreased. It was determined that delamination values in glass fiber reinforced composites decreased as the feed rate increase, while delamination values increased as the cutting speed increased. Generally, the thrust forces, vibration, delamination, and moment values obtained during the drilling of B4C-filled glass fiber composites were found to be higher compared to Gr-filled glass fiber composites.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"145 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study examines the consequences of expanding the size of the chimney and the quantity of TEGs, and it finds benefits for power generation. However, using fans reduced the amount of electricity generated to 30.58 W, 27.83 W and 24.92 W were recorded for the first, second and third fan speeds, respectively. The highest power production is notably correlated with larger temperature differences; for the 90 TEG modules, a maximum of 37.85 W was recorded at zero fan speed.

Large-scale sensor networks comprise numerous nodes capable of collecting homogeneous data from multiple sources and multiple modes. However, due to constraints on node bandwidth and energy, transmitting all data to a server would result in significant resource wastage. Furthermore, environmental noise and node failures make it challenging to ensure data reliability. Consequently, the quest for acquiring high-quality information from sensor networks while adhering to resource constraints has become an urgent issue. This paper focus on two aspects of data quality: reliability and sharing. Reliability is quantified by the deviation of data from ground truth, with smaller deviations indicating higher reliability. Sharing refers to the strong data correlation among neighboring nodes. Therefore, this paper constructs an optimization model that, under constraints related to energy and sharing, selects the most reliable data sources to transmit, maximizing the reliability of homogeneous multi-source, multi-modal data. Through experiments, genetic algorithms in sensor networks achieved a maximum improvement of 18.7% compared to the baseline in terms of data bias and a maximum improvement of 22.8% in terms of data reliability, offering an effective means for critical information acquisition in sensor networks.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"145 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141867866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their many advantages, a WE system based on a doubly fed induction generator is vulnerable to power grid disruptions. Due to being built on traditional controllers, the generator systems with standard vector control (VC) cannot resist disturbances. This paper seeks to provide a novel VC that is resistant to outer perturbations. For this purpose, a finite state space model predictive control (FS-MPC) is utilized instead of the internal current loop of the standard VC. The objective of the proposed system is to minimize the error between the measured currents and their reference values and, also, reduces the total harmonic distortion (THD) of the current. The cost function can optimize this requirement, which reduces the computation time. The VC-FS-MPC was implemented using the MATLAB, where a 1.5-MW generator operating under different conditions was used. The necessary graphical and numerical results were extracted to show the efficiency, effectiveness, and ability of the VC-FS-MPC to improve the characteristics of the studied energy system. The results show the flexibility and distinctive performance of the VC-FS-MPC in the various tests used, as the THD of stator current was reduced in the second test compared to the first test by an estimated percentage of 61.79%. Moreover, the THD of rotor current was reduced compared to the first test by an estimated percentage of 23.56%. These ratios confirm the effectiveness of the VC-FS-MPC in improving the characteristics of the proposed system.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"74 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141867868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These components include the impeller, diffuser, and volute. However, there is a limited number of published papers studying the combined performance of individually optimized components working together. This article presents a hierarchy optimization approach conducted on a turbocharger compressor, composed of two or three individually optimized components including two optimized impellers, one vaned diffuser and one optimized volute, each with distinctive optimization method. The article also reports the resulting improvements in pressure ratio and overall isentropic efficiency of the machine, by means of investigations of nine different compressor configurations, including the original design. Experimental tests are performed at several rotational speeds and different mass flow rates to generate compressor performance maps. To simulate the compressor flow field, a three-dimensional steady-state compressible turbulent flow simulation code is employed and evaluated with experimental data. The results show that a configuration using an optimized impeller, vaned diffuser, and an optimized volute, improves efficiency and pressure ratio up to 11.3% and 16.5%, respectively, which are significant enhancements and important achievements. A detailed examination of the flow field reveals that in this particular configuration, pressure fluctuations at the impeller exit decrease by 71%, and the average pressure at the impeller exit increases up to 46% compared to the original design. Furthermore, flows in the impeller passages become more uniform, with limited separation regions near the trailing edge of blades.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"46 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The specific manifestations are: Firstly, the hydraulic jump is oblique, and when the upstream energy exceeds a certain value, a hydraulic jump occurs on the obtuse angle side formed by the starting section, while no hydraulic jump occurs on the other side. And there is a large difference in the water level between the longitudinal and cross sections in the stilling basin, and the smaller the angle, the greater the difference caused. Secondly, the water level on the obtuse angle side is higher than that on the acute angle side, and the smaller the angle, the greater the change, with the lowest water level occurring on the acute angle side; the oblique angle of the stilling basin causes uneven energy at the starting section, with greater energy on the acute angle side than that on obtuse angle side, and smaller angles have greater energy.

A cost-effective technique to mitigate build-up heat and improve the thermal cycle is accomplished with the introduction of an inter-layer dwell time (ILDT). The study investigates the impact of ILDTs of 60, 90, 120, 150, and 180 s on the properties of the printed parts. The grain refinements were achieved at higher ILDT with no appreciable changes in the compositions. However, a slight increase in oxides and (delta )-ferrite was detected. The study found improved part density, mechanical and tribological performance while reduced corrosion-resistant properties with increased ILDT. Furthermore, to understand the effect of ILDTs on location-based thermal cycling and distribution, numerical models of the process were established. The peak temperature gradually reduces with an increase in ILDT. Heat accumulations within the three-layered WAAM-built structure lessen by 70% approximately with increases in ILDT from the 60 s to 180 s. The results observed repeated thermal cycles of the previously deposited layers and reduction of peak temperatures with subsequent layer deposition irrespective of the ILDTs. The trough temperature slightly reduced with ILDT; however, at higher delay periods the variations were found to be more stable. The study discovered too low and too high ILDT is detrimental and therefore an appropriate mid-range ILDT of 120 s is suggested to fabricate medium-size WAAM-built components based on experimental and numerical investigation considering overall production time and functional properties.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"171 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is still a challenge for most existing vision-based methods to segment terrains with satisfactory accuracy and real-time performance. Deep learning-based approaches have been proven to be quite competitive for image segmentation. However, most previous segmentation networks have deep networks and explosive growth of the number of parameters, which can hardly satisfy the inference speed of onboard computers. Therefore, a novel terrain segmentation method founded on CSPResnet is designed for segmenting terrains of field robots in this study. It fuses some advantages of several state-of-the-art networks and has a novel structure suitable for on-board computers. The proposed method reduces the computational cost for segmenting terrains by cross-stage partial, spatial pyramid pooling, and nearest interpolation. Finally, some comparison and ablation studies were made on the HDU-Terrain dataset. We collected this dataset from a field robot’s perspective. It is quite different from the existing benchmark dataset for unmanned driving and has more than 4000 frames of pixel-wise annotation, with many frequently encountered unstructured terrain types.
