Abstract The electrical and mechanical characteristics of a cylindrical electrohydrodynamic pump are discussed in this paper. The air flow in this pump is produced by the surface dielectric barrier discharge generated between two strip electrodes attached to a hollow dielectric cylinder. The pump characteristics are predicted by simulating the ionized electric field (non-thermal plasma) and the air flow. A quasi-stationary plasma model is approximate and involves two ionic species. However, their full spatial and temporal distributions are calculated by solving the Poisson and charge transport equations using the Finite Element Method. The pump electrical (electric power) and mechanical (body force, velocity distribution, volume flow rate, output mechanical power, efficiency) parameters are presented for different magnitudes of ac voltage, its frequency, pump geometry and operating conditions. Simulations were based on combination of the COMSOL and ANSYS/FLUENT commercial software.

基于表面介质阻挡放电的电流体动力泵二物种建模

摘要 本文讨论了圆柱形电流体泵的电气和机械特性。该泵中的空气流是由连接到中空介质圆柱体的两个带状电极之间产生的表面介质阻挡放电产生的。通过模拟电离电场（非热等离子体）和气流来预测泵的特性。准稳态等离子体模型是近似的，涉及两种离子种类。然而，它们的完整空间和时间分布是通过使用有限元方法求解泊松方程和电荷传输方程来计算的。泵的电气（电力）和机械（体力、速度分布、体积流量、输出机械功率、效率）参数针对不同大小的交流电压呈现，其频率、泵几何形状和运行条件。仿真基于 COMSOL 和 ANSYS/FLUENT 商业软件的组合。
