摘要

采用烟丝法对电动汽车(EV)虚拟电池模块上游三种不同类型的v形涡发生器(VGs)诱导的反向旋转涡的流向发展进行了实验观察。从单一的chevron参考情况来看，蘑菇状的涡旋在通过模块之前不会坍缩。线形线使用越多，旋涡越明显。还可以观察到旋涡的大小和形状受旋涡沿展向基底长度的显著影响。这三个VGs的诱导涡表明，在电动汽车电池模块的应用中，潜在的热传递增强了。

VISUALIZATION OF INDUCED COUNTER-ROTATING VORTICES FOR ELECTRIC VEHICLES BATTERY MODULE THERMAL MANAGEMENT

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.
