摘　　要：本文基于Reyleigh整流定律,利用ψ-ω形式的定常不可压N-S方程,数值模拟了双柱在圆域内作高频小振幅振动时所产生的定常整流流动。揭示了流动随整流雷诺数的演化特性。此外就求解ψ-ω形式的N-S方程所涉及的定解边界条件问题。This paper deals with the steady streaming flow caused by oscillating double circular cylinders in a circular region. Based on the Rayleigh streaming law and steady incompressible N S equation in the ψ ω form, the flow is numerically simulated.The evolution of flow patterns with the streaming Reynolds number is analyzed. In addition, the involved boundary conditions are also discussed.
