In the present report,incompressible flow fields around a two-dimensional cylinder parallel moving near the side wall are numerically simulated by the vorticity stream function formulation at the condition of pressure single-valuedness. The present results show a good agreement with experimental result and well confirm the vorticity stream function formulation at the condition of pressure single-valuedness.%采用边界压力单向条件的流函数-旋度方程,对在不可压缩流体中贴近墙面平行移动的圆柱体周围的流场进行了二维数值仿真.计算结果与实验结果有较高的一致性,证明了在边界压力单向条件下流函数-旋度方程的有效性.
