摘　　要：为研究电场对气体对流换热的影响,依据场域控制方程,建立了表征电场及电荷密度分布的数学模型,并利用场线坐标法对线-板电极系统的电场、电位及电荷密度的分布进行了数值模拟,得到了场域空间单相气体所受电场力的分布情况.模拟结果显示,有电晕放电产生的电场可引起场域空间气体的“紊流”,并导致对流换热的增强.In order to investigate the effect of electric field on gas convection heat transfer, the mathematical model of the distributions of electric field and charge density was established on the basis of field domain governing equations, and the electric field lines coordinate method was employed to simulate the distributions of electric field, potential, charge density and force exerted on the single phase gas in the wire-plane electrode numerically. The computing results indicate that electric field with corona discharge can cause the turbulent flow in the space and result in convection heat transfer enhancement in gas.
