The present numerical study has been carried out to find the most appropriate obliquity/incident angle which can effectively be used for design of protective armor. Although it is not possible to practically control the incident projectile angles, but numerical investigation can potentially provide solution for design and performance optimization of overall structure and surface geometry of target plate, or adaptive adjustment in terms of target obliquity angle.

Blowing agent supplies air inside the parent metal, and metal foam has emerged to be a promising material because of its low density, high absorption capacity, low thermal conductivity and high strength which finds its huge applications in automobile components. The present work deals with the application of the aluminium metal foam with different densities 200 and 400 kg/m<sup>3</sup> in automobiles. Various tests such as toughness, hardness, bending and compression are carried out for four chosen densities, and the values are compared with the aluminium base metal. The result showed that the hardness value increased significantly by 24.48% with the rise in the density from 200 to 400 kg/m<sup>3</sup>. Maximum modulus of resilience for the low-density specimen is found to be 2.21 MJ/m<sup>3</sup>. Surface topography showed irregular pore shapes with discontinuity, resulting in a loss of cell integrity with the neighbouring cell walls. This affected the performance of the foam significantly. Thermal experiments were carried out to determine the thermal conductivity where thermal conductivity increased by 122% with the rise in the density from 200 to 400 kg/m<sup>3</sup>. Based on the results, it is concluded that aluminium foam with density 400 kg/m<sup>3</sup> can be recommended for use in automobile applications due to its lightweight properties, which contribute to improving fuel efficiency, impact absorption capacity and the vehicle’s speed. Additionally, the air trapped within the foam cells serves as a sound barrier and insulator in cars.</p>","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"38 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141932899","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}

Under conditions of both uniform and non-uniform temperature distributions on both sides of the slab, the effects of misalignment of incoming slabs and misalignment of anvils on the camber are discussed and compared. Results indicate that the impacts on cambers can be prioritized in descending order: anvil horizontal tilt, slab centerline offset, slab horizontal tilt, and anvil centerline offset. Further research reveals that when the uneven temperature is coupled with these asymmetric factors, maintaining the influence value within 30 mm, and positioning the high-temperature side of the slab on the side opposing the tilt direction, while aligning the offsets of the slab and anvil in the same direction contributes to reducing the camber. Besides, by controlling the slab heating process and implementing related precision control measures for the sizing press, the cambers of the sizing slabs can be significantly reduced.

This study proposes a novel application of partial update Kalman filter (PUKF) where the PUKF profoundly enhances the accuracy of bilinear systems modelling. In the PUKF approach, only a subset of the parameter state vector is updated at each epoch, which could decrease the computational burden compared to the traditional Kalman filter. Moreover, this work uses a preaching optimisation algorithm (POA) to tune the PUKF parameters adaptively based on the estimation problem. The adequately adjusted adaptive PUKF provide good estimation results, stable filtering operation and quick convergence. A new objective function is formulated based on correlation functions and an error between the estimated and actual outputs. The new objective function significantly improved the quality of the solution. The sensitivity of POA on solution quality is analysed using various statistical parameters. The efficacy and correctness of the proposed algorithm are verified on a numerical plant and two real-time benchmark systems. The quantitative analysis based on the proposed scheme is examined with distinct standard metrics and robustness verified at different Gaussian noise variance levels. The accuracy, stability, and consistency of the proposed algorithm performance are verified through the Diebold–Mariano hypothesis test, results from several independent runs, and tenfold cross-validation tests. The simulation results manifest that the POA-assisted PUKF method is much more effective and better compared to other existing and employed benchmark metaheuristic techniques such as self-adaptive differential evolution, crow search algorithm, and POA methods.</p>","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"45 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141882558","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 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.
