| 摘 要： | 利用等离子体进行流动控制是当前的研究热点之一.本文研究通过数值方法模拟等离子体对流场作用的实现方法,及利用数值模拟方法研究翼型大迎角分离流动的等离子体控制.利用CFD软件Fluent中的自定义函数接口,通过C语言编程在软件中引入DBD等离子体激励模型外加体积力源项,对NACA0015翼型大迎角下的等离子体控制进行数值模拟.验证DBD等离子体激励在抑制流动分离与增升减阻方面的作用.结果表明：流动控制效果与DBD激励器布置位置有直接关系;激励器的数量与激励强度均会影响流动控制作用.

| Abstract: | The application of plasma actuators for flow control is one of the most popular researches nowadays. By using numerical simulation, this paper mainly studied two things: the method of simulating the effect of plasma actuators on flow fields; the plasma control of airfoil separated flow at large angles of attack. In this paper, a simplified model for plasma actuators is presented using FLUENT UDF to numerically simulate the plasma control of NACA0015 airfoil at large angles of attack. The results show that DBD plasma actuators can delay flow separation, increase the lift, and decrease the drag of the airfoil. Based on the analysis of numerical results, this paper also discusses the effect of the location, number, and strength of plasma actuators on flow separation. |
