The jet flow on vibration wall in tube was simulated based on solving the two-dimensional incomperssible Reynolds averaged Navier-Stokes equation with moving grid and k－ε two-equation turbulence model.The influences of amplitude and frequency of wall vibration on the flow were discussed.The results show that the static pressure on the wall at the jet hole downstream increases with the increase of the amplitude and frequency.The static pressure reaches the lowest under the phase angle of 126 °.The average flow rate of the jet flow decreases with the increase of the amplitude,but increases with the increase of the frequency,and the flow rate fluctuation increases with the increase of the amplitude and the frequency.High frequency has more obvious effects on the mainstream.
