新型等离子体激励器的数值模拟

为了对新型多电极对等离子体激励器进行可靠的数值模拟，通过求解带有体积力源项的Navier—Stokes方程，模拟单电极对等离子体激励器在二维不可压流中对周围流场的影响，计算结果表明所使用唯象模型的参数基本正确。在此基础上，改进原有模型，对新型双极性等离子体激励器诱导流动进行计算。通过与实验结果的对比，发现改进后的模型能较好地模拟新型双极性等离子体激励器的控制作用，可为今后新型等离子体激励器的应用提供可靠的数值模拟方法。

Numerical Simulation on Flow Based on New Kind of Plasma Actuator

In order to get reliable numerical simulation of the new multi- bipolar plasma actuator, firstly, the flow induced by single electrode plasma actuator in two dimensional incompressible flow is simulated by adding the body force source term to the Navier- Stokes equations. The results presents the parameters of a phenomenological model we used are basically correct. On this basis, the flow induced by the new multi- b~polar plasma actuator is simulated by improving the original model. Comparing computational re- suits with experimental results, we find that, with the improved model, the flow controled by the new multi - bipolar plasma actuator can be well simulated, which results in providing a reliable numerical simulation method for future applications of this new plasma actuator.
