摘要：

The role of vw at a fixed value of σ was tested for blowing/suction. Toward this end, a direct numerical simulation of turbulent boundary layer was performed at Reθ=300. The results for three different values of vw at a constant |σ|=0.322 reveal that |Δ'w.rms| and |∫(∂P/∂x)dy| increase with increasing |vw| above the slot. A local maximum was found to exist after the slot for blowing.
