摘要

利用已有的Navier-Stokes解算器对微合成射流执行器内部和周围的流场进行了分析。对求解器进行了改进，以适应文献中提出的微尺度流动问题的滑移壁边界条件。研究了静态和跨流外域条件下的矩形和三角形两种致动器腔体形状。给出了滑移和无滑移条件下的结果并进行了比较。发现空腔形状会影响孔板排烟速度分布。横流不仅影响孔板的速度分布，而且影响腔内的流场。

Micro synthetic jets and their interaction with a cross flow in slip regime

The flow field generated in and around a micro synthetic jet actuator is analyzed using the an existing Navier-Stokes solver. The solver is modified to accommodate slip wall boundary condition proposed in literature for micro scale flow problems. Two actuator cavity shapes, rectangular and triangular, are investigated for quiescent and cross-flow external domain conditions. Results are presented and compared for slip and no-slip conditions. Cavity shape is found to affect the orifice expulsion velocity profile. Cross-flow affects the orifice velocity distribution as well as the flow field inside the cavity.
