my.uniten.dspace-351762024-12-01T02:01:30Z Numerical investigation of heat transfer and fluid flow characteristics at different oblique fin arrangements in Liquid Cold Plate LCP Fatin Fatihah Abdul Majid Electric vehicle TL220.F38 2018 This thesis analyses and demonstrates the variation of arrangements that can be made for fins used in Liquid Cold Plate (LCP) for Electric Vehicle (EV). The analysis comprises study of temperature and velocity contour for the fluid in the LCP, with various conditions. These conditions are different velocity and different arrangement for fins in the LCP. Li-ion battery happens to get burnt or catch fire where this can be seen in a few cases of EV made by Tesla and Boeing. This is due to the overheating of the battery with inefficient cooling system. The numerical investigation is done in CFD software, specifically ANSYS Workbench 18.1. The shape of the fins used for this paper is the oblique shaped fins. Primarily, three different arrangements are selected for the investigation. These arrangements are inline, incline and louvered where all three uses the same set of LCP, batteries and fins dimensions. Parameters such as the heat flux and convection rate are constant throughout all the cases. Ethylene glycol is chosen for the fluid domain in the LCP, flowing between two heated surface at its top and bottom, passing the array of fins. Additionally, the LCP has the same two inlets and outlets where the velocity of coolant flowing varies from Re-200 with an increment of 200 to Re-1000. The relationship between battery surface temperature, fluid temperature, heat transfer coefficient and Nusselt number with Re are studied. From this investigation it was found that better heat transfer occurs at higher velocity. Other than that, based on the results obtained from the three arrangements, louvered type arrangements presented the best heat transfer followed by the inline and incline arrangement. Fluid flow mixing effect is better at high velocity and in louvered arrangement. In addition, desired battery surface temperature is accomplished with high velocity and in louvered arrangement too. All works done are shown with clear explanation, citation and aided with figures and charts. 2024-11-29T02:47:15Z 2024-11-29T02:47:15Z 2018 Resource Types::text::Final Year Project https://irepository.uniten.edu.my/handle/123456789/35176 en application/pdf |
