The simulations are conducted for the pertinent parameters in the following ranges: the Reynolds number Re=50-300, the gap ratio G/d = 2, and the splitter's inclination angle 8 = 0°-90°. The results show that with the increase in the angle of the splitter, the drag coefficient initially decreases and then increases. Moreover, the time-averaged Nusselt number at a certain angle increases noticeably.展开更多
