中文摘要：

本文应用多物理场耦合计算软件COMSOL对离子风作用下强化平板对流换热的过程进行了数值模拟。研究了空气在高压电场下的对流换热现象，得到线一板电极模型相应的流场和温度场分布，并与文献中的实验结果进行了对比，验证了多物理场耦合数值方法的准确性。通过研究不同电压下传统风扇风冷、离子风和离子风与风扇共同作用下的对流换热系数变化规律，发现空气放电强化传热较传统方式有明显优势。还研究了不同极板距与板长比和不同板长情况下对流换热系数的变化规律。

英文摘要：

The process of convective heat transfer enhancement of a heated plate by corona wind is investigated with the commercial code COMSOL Multiphysics. The convective heat transfer phenomenon of the air under high voltage electric field is studied, and the distribution of the flow field and the temperature field for the line-plat model are obtained. The numerical method is verified to be reliable by comparing with the experimental results. It is found that corona wind in enhancing heat transfer possess obvious advantages than traditional way by studying the heat transfer coefficient under the action of traditional fan, corona wind and the combine of corona wind and traditional fan. In addition, the change laws of convective heat transfer coefficient in different polar-plate distances, plate length ratios and plate lengths are also considered.
