摘要: 通过求解电场中的拉普拉斯方程和赫姆霍兹方程的变形形式,成功地将等离子体激励对平板附面层流动的影响,以体积力向量的形式引入到NS方程之中.借助求解的电荷密度,通过将计算结果与实验数据的对比,可确定德拜长度、最大电荷密度、形状因子等可调参数的取值原则,建立起平板附面层等离子体流动控制的数值模拟方法,为将等离子体流动控制方法应用于外流及内流场中的强剪切流动控制,奠定关键性的技术支撑.

Abstract: Through Laplace equation and transformed Helmholtz equation in the electric field,this paper simulated successfully the plasma flow control in the flat plate.Abody force vector was introduced to the Navier Strokes equations to simulate the effect of plasma actuation on the flow.Debye length,maximum charge density and scale parameter,etc,could be determined by comparing the calculated result with experimental data.This helps to establish a numerical simulation method for flat plate plasma flow control,thus providing a crucial technical support for applying plasma flow control into external and internal sharp shear flow.
