Abstract A simple model for simulating the surface plasma-induced jets is proposed. The characteristics of the wall jet are estimated based on thrust imposed by the plasma and then related to the similarity solution for the viscous wall jet problem to obtain a plasma wall jet velocity profile. Then the plasma-induced flow field outside the plasma discharge region is simulated by simply imposing a plasma wall jet velocity profile in a single streamwise location. The validity of the model for simulating the effect produced by the dielectric barrier discharge (DBD) plasma actuators is tested against some experimental and numerical simulation results.

使用壁射流相似性方法的 DBD 等离子体致动器的显式 CFD 模型

摘要 提出了一种模拟表面等离子体诱导射流的简单模型。基于等离子体施加的推力估计壁射流的特性，然后关联粘性壁射流问题的相似解以获得等离子体壁射流速度剖面。然后通过在单个流向位置简单地施加等离子体壁射流速度分布来模拟等离子体放电区域外的等离子体诱导流场。用于模拟介质阻挡放电 (DBD) 等离子体致动器产生的效应的模型的有效性通过一些实验和数值模拟结果进行了测试。
