混合对流发生在较低流动的加热(或冷却)流道内,流动由外加压力梯度和浮升力共同支配。此时,浮升力的存在使流场中切应力分布与等温流动时的有本质不同,传热和流动特性更为复杂。
Mixed convection occurs in the lower flowing heated (or cooled) flow path and the flow is dominated by applied pressure gradients and buoyancy forces. At this moment, the existence of the buoyancy force makes the distribution of shear stress in the flow field essentially different from that at isothermal flow, and the heat transfer and flow characteristics are more complicated.
