| 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. |
