Numerical Simulation on Convective Heat Transfer Enhancement of a Heated Plate in a Channel by Corona Wind

本文采用COMSOL Multiphysics软件对离子风强化通道内平板对流传热进行了三维数值模拟研究。文中研究了离子风作用下通道内的速度场和电场力的分布情况,同时还对比研究了三种不同流动情况下对流传热系数的变化规律。研究结果表明电场力是影响离子风强化传热效果的一个重要因素。

Three-dimensional numerical simulation on the process of convective heat transfer enhancement of a heated plate in a channel by corona windwasconducted by using commercial code COMSOL Multiphysics.In this paper,the distribution of velocityand electrical forcein the channel were studied,and the variation of convective heat transfer coefficientunder three different flow conditions were investigated.The result reveals thatthe electric force is an important factor affecting the enhancement ofconvection heat transfer by corona wind.
