摘　　要：本文证明了文献［１０］所述的求解二维Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程的边界元方法在高Ｒｅ下仍是稳定的。作为示例，本文给出了方腔拖动粘性流在Ｒｅ＝１００００下的收敛解。该解与差分法所得结果相吻合。The high-order BEM formulations for 2D N-S equations describe in [10] are proved to be stable for high Re number. As an example, the convergent results of the shear-driven viscous flow in a square cavity in the case Re=10000 are obtaied, which agree well to those Obtained by FDM.
