利用微气囊扰动进行流动控制的数值模拟研究

The simulation of fluid control by microactuators

探讨一种可以用来模拟“三角翼上分布微气囊 ,从而控制流动获得滚转力矩”的数值方法。为微型飞机的气动设计提供一种工具。研究的内容包括 :考虑微气囊的三角翼网格生成、流场NS方程计算、微气囊不同布局对流动的扰动等。

In this paper, a CFD technique is discussed, which is used to simulate a delta wing fluid field with microactuator on it for the purpose of flow control to get an additional roll moment. The method can be helpful for the areodynamics design of micro aircraft. The content of the paper include:grid generation considered microactuators; simulation of flow field controlled by NS equations; the influence to roll moment under different position of microactuator.
