矩形纵向涡发生器平板强化换热的实验研究

An Experimental Study on the Enhanced Heat Transfer of the Plane Plates in the Rectangle Longitudinal Vortex Generators

利用热质比拟萘升华技术，在吸入式风洞中对矩形纵向涡发生器平极强化换热进行了实验研究。在雷诺数范围2．3×10^5～5．4×10^5内，通过改变涡发生器迎流冲击角卢，得到强化换热的效果，并对参数进行优化。

An experimental study was performed of the enhanced heat transfer of the plane plates in the rectangle longitudinal vortex generator in a suction-type wind tunnel using heat and mass to analogize the naphthalene sublimation technique. Within 2.3×10^5 - 5.4×10^5 of Reynolds number, the enhanced heat transfer efficiency was obtained by varying the angle of attack of the vortex generator, and the parameters were optimized.
