摘要
本文依据牛顿流体中建立的标准ｋ＿ε湍流模型这一基本思想，考虑宾汉流体的本构方程，建立了适用于求解宾汉流体湍流流动的控制方程·采用压力修正算法，实现了宾汉流体速度场与压力场的关联·在理论研究基础上，对直圆管突扩通道内宾汉流体湍流流动进行了数值研究，并探讨了直圆管突扩通道内宾汉流体湍流流动机理·
The control equations for the turbulent flow of Bingham flulid are established according to Bingham fluid constitution equation. Pressure field and velocity field are correlated by pressure_correction equation. The numerical computations are performed on Bingham fluid turbulent flow in sudden_expansion straight circular pipe, and the flow mechanisms are discussed.
