| 摘 要： | 通过求解电势方程和电荷密度方程得到了等离子体对周围空气施加的电动体积力的分布;借助电子天平测力实验对电动力的水平方向分力进行了实验研究;单摆实验则进一步认识了尖端电极放电所产生的推力。数值模拟结果表明电动力集中裸露电极边缘以及等离子体生成区域附近;实验结果表明电动力水平方向分力与激励电压之间是线性关系、电极的连接方式对电动力有很大影响。

| Abstract: | By solving the electric potential equation and charge density equation,the electrohydrodynamic body force exerted on the air by the dielectric barrier discharge was determined. Horizontal component of the electrohydrodynamic force was investigated experimentally by electric balances. The thrust of point electrode discharge was measured in a pendulum experiment. Numerical simulation results show that the body force is concentrated near the exposed electrode edge and plasma region. Experimental results show that the relation between exciting voltage and horizontal component of the electrohydrodynamic force is linear. Mechanical characteristics of DBD plasma may be affected greatly by the mode of electrode linking. |
