One of these passive enhancement methods is to use vortex generators (VG). This study is devoted to the heat transfer enhancement in a laminar parallel plate flow using rectangular wing VG. Three-dimensional numerical simulations are performed to study the effect of the angle of attack of the VG on the heat transfer and pressure drop. For this aim, Nusselt number and friction factor are studied on global perspectives. For all the values of angle of attacks the flow regime is kept laminar. Based on global parameters, it is found that the angle of attack has a direct impact on the heat transfer enhancement. By increasing this value, the global Nusselt number and the global friction factor are increased. This increase leads to a better enhancement until it reaches an optimal value for an angle of attack of 25°, beyond which the thermal performance starts to decrease.","PeriodicalId":220936,"journal":{"name":"2016 3rd International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132100691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This simulation entails the modeling of four main components: an electrochemical hydrogen production cell with a thermal model, electrochemical compression and storage, and optimal car fueling. In the electrochemical cell model, an equivalent circuit for the PEM electrolyzer is built to compute the total electric energy needed for a certain demand of hydrogen. Moreover, the effect of temperature on the efficiency of the electrolyzer is modeled and accounts for the energy exchange process and temperature increase or decrease during electrolysis. Furthermore, a cooling system was developed in order to maintain the cell at optimum operating conditions, and thus operate at maximum efficiency. The hydrogen produced needs to be compressed because of its low volumetric density before it can be used for fuel cell cars. The compression is carried out using an electrochemical compressor. The advantages of this compressor are highlighted and its operation is compared to that of a mechanical compressor regarding efficiency and stability. Furthermore, the issue of back hydrogen diffusion in the compressor is analyzed and its effect on the efficiency of the system assessed; this effect was modeled for different types of membranes of different thicknesses. Finally, a procedure is presented for an automated filling station, and its various control measures are considered in order to maintain an efficient filling operation within the safety limits of the tank.","PeriodicalId":220936,"journal":{"name":"2016 3rd International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133935514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Satellite TV requires a receiver and a satellite dish which must be pointed to a certain satellite in the sky. Dish pointing is a tricky process that requires the presence of a technician. This makes satellite TV impractical and problematic for people who live on caravans or do long road trips, for they are forced to stick with terrestrial broadcasting. However, auto-aligning to satellites using advances in the automation field can solve the problem of dish pointing. Accordingly, this project presents SatFinder; a novel solution to the problem of dish pointing. The solution enables any user, while outdoors, upon choosing a location, to point the satellite dish to any satellite covering that region with just a few clicks from the mobile phone. This system consists of a satellite dish position controller made up of stepper motors, position sensors, and a microprocessor, connected to a mobile application through Bluetooth from which the controller takes the user input, which is the desired satellite to be pointed to. The controller analyzes the system's position using a GPS sensor, and drives the satellite dish to specific azimuth and elevation angles computed via a mathematical formula that relates the GPS position to the desired satellite degree. In this paper, a smart auto alignment satellite downlink system is designed and implemented to ease the access of satellite TV. Satellite downlink systems exist widely but very few are automated and can achieve auto-alignment to satellites. SatFinder, by achieving the auto-alignment, enables people who live on caravans or do long road trips to access satellite TV anywhere they would be.","PeriodicalId":220936,"journal":{"name":"2016 3rd International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"72 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124807624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AGI Supersting R1/IP was used for data acquisition and data were processed by an iterative finite element based inversion algorithm with EarthImager 2D. 1D testing was also performed on concrete cylinders with two stainless steel plates located at the ends acting as a source and a receiver. ERTs and 1D results showed that the electrical resistivity of concrete was lower in specimens with PET than in those without PET. After ERT testing, compressive strength tests were conducted on specimens. Findings revealed an increase in the compressive strength up to a PET content of 5% then a decrease up to a PET content of 20%. Findings also showed that the inclusion of PET increased the probability of corrosive action in PET concrete.","PeriodicalId":220936,"journal":{"name":"2016 3rd International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129926550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The axial and the torsional behavior of composite tubes of circular cross-section, comprising a casing and an infill, is addressed analytically, to develop physical insight into the mechanical interactions between these two components, in the linear range. The influence of the material parameters of the infill, relative to those of the casing, and of geometry - such as the ratio of wall-thickness to diameter of the casing - on the structural stiffness and capacity of the composite are revealed and presented in a novel graphical form. It is shown that significantly improved overall stiffness and capacity at yield can be obtained by bonding a moderately softer, but highly auxetic, infill to the casing, which highlights the need to develop new lightweight auxetic materials, without compromising their stiffness. These predictions are verified in torsion and confirmed in bending by means of suitable computational models based on the finite element method.","PeriodicalId":220936,"journal":{"name":"2016 3rd International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"20 23-24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123595162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
