Abstract Streamwise development of counter-rotating vortices induced by three different types of chevron Vortex Generators (VGs) placed upstream an
Electric Vehicles (EV) dummy battery module is experimentally visualized using a smoke-wire method. From the single chevron reference case, the
mushroom-like vortices do not collapse until passing the module. When more chevrons are used in line, the vortices become more prominent. It can
also be observed that the vortex sizes and shapes are significantly influenced by the spanwise base length of the chevron. The induced vortices from
all three VGs suggest a potential heat transfer augmentation for the EV battery module application. More >
