【摘要】 研究不可压缩流体流经圆柱体底部时，形成的底部流动，其数值方法可采用由D．B．Spalding、S．V．Patankar发展起来的控制体积分方法。计算模型中，引入了二方程湍流模型（即κ-ε模型）。数值计算结果与实验结果吻合良好，更多还原

【Abstract】 This paper studies the base flow caused by the incompressible fluid past through the cylinder base. The control volume method of integral developed by D. B. Spalding and S. V. Patankar is used. The two equations of turbulence model(the к - ε model) are introduced to the computational model. The obtained numerical results fit the experimental results well.更多还原
