摘要/Abstract

摘要： 通过数值求解Navier-Stokes方程模拟零质量射流对低雷诺数翼型绕流的控制作用.空间离散采用中心有限体积格式，时间推进为双时间推进方法.计算结果表明，采用零质量射流进行主动流动控制能有效抑制大攻角下大尺度的流动分离，改善翼型的气动特性，起到显著的增升减阻作用.

关键词: N-S方程, 零质量射流, 微型飞行器, 主动流动控制

Abstract: The control effect of zero-net-mass-flux jet on the viscous flow around airfoil has been simulated using N-S equation. In the solver, the cell-centered finite volume method in space and dual-time stepping method in time is used. The results show that active flow control can enhance aerodynamic performance by reducing the adverse effects of separated flow.

Key words: active flow control, N-S equation, zero-net -mass-flux jet, MAV
