摘要
用数值模拟法研究了水平同心套筒内、外筒加热旋转时的流动和传热特性,提出了旋转流抑制自然对流的物理机制,进一步验证了对流换热可比拟为具有内热源的导热问题。
A numerical investigation of the flow and heat transfer of air in the annulus be-tween horizontal concentric cylinders with one cylinder heated and rotating is carried out.The mechanism of the suppression of natural convection by fluid rotation is advanced.It is proved that the convection heat transfer can be regarded as a conduction problem with heat sources(orsinks).
