Applied Thermal Engineering, Volume 211, July 2022, Article number 1185061359-4311https://doi.org/10.1016/j.applthermaleng.2022.118506http://dspace.lib.cranfield.ac.uk/handle/1826/17810Computational Fluid Dynamics has emerged as one of the major investigative tools for aerodynamics and thermal analyses of today’s road vehicle design processes. This work presents the design of a new heat exchanger layout that could support the transition from thermal to electrical propulsion of an existing motor vehicle. A procedure is established to develop and assess a heat exchanger prototype. The aerodynamic performance of an electric vehicle equipped with the above-mentioned heat exchanger is assessed numerically, and results compared with its thermal counterpart. The comparison between both layouts shows a 5% reduction of the vehicle’s drag and a net reduction of the overall weight with the newly designed system, introducing the proposal for a new form of heat exchanger packaging.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/OpenFOAMk-omega SSTHeat exchangerDrag coefficientArticle
