摘要
本文提出了流动与换热中的各种场的协同,会影响流动和换热的稳定性这一新观点。通过对带有倾角的方形空间自然对流换热及具有对称射流的方形空间内混合对流换热问题的数值计算可以发现,这两个流动换热的例子中,流场、温度场、重力场的协同能够影响其流动与换热的稳定性,这初步验证了本文提出的这一观点。
This paper gives a new idea that synergy between the physical fields in convection heat transfer is able to influence the stability of the convection heat transfer. To investigate the field synergy and the stability, numerical simulations are performed for a natural convection heat transfer in a rectangle cavity with an angle of inclination and a mixed convection heat transfer in a rectangle cavity with symmetric upper jets. It can be found that the synergy between velocity and temperature and gravity field...
