中文摘要：
基于不同等离子简化模型,对比研究了5 kV电压下等离子诱导流场。结果表明,由于假定电荷分布依赖于电势分布,模型一导致体积力过大,诱导流场速度最大达6 m/s;模型二中内外电场叠加并根据实验拟合壁面电荷分布,最大诱导速度仅为1 m/s,与实验结果接近;而模型三由于不易选取合理的电场强度分布线性化参数,最大诱导速度达7 m/s,也与实验结果相差较大。
英文摘要：
Based on the different plasma simplified models, a contrast study of induced flow under a voltage of 5 kV was carried out. The results indicate that, the charge density was assumed to rely on the electric potential distribution directly in the first model, which causes the body force to be aggrandized, thus the induced flow velocity reaches 6 m/s. In the second model, the inside and outside electric field was summed and charge density was pinned according to the experiment, the maximum induced velocity is only 1 m/s, which is close with the experimental result. While in the third model, it is not easy to select the reasonable parameters to linearize the electric-field intensity, the maximum induced velocity reaches 7 m/s, which is different from the experimental result.
