Numerical simulation of the zero mass jet flow

Numerical simulation methods are used to investigate the actuator of zero mass jet flow and the flow around airfoil with zero mass jet flow.The effects on the actuator of zero mass jet flow are analysed about dynamic grid,geometry conservation law,numerical boundary conditions,and turbulence mode.And the effects on increasing lift are analysed also,including the jet flow velocity and frequency.The results indicate that numerical boundary conditions of the actuator of zero mass jet flow can be treated with given numerical value for complicated calculation,both the average lift coefficient and the average drag coefficient are added with the increase of the jet flow velocity,and the effects of the jet flow frequency on lift are non-linear.
