摘要
考虑宾汉流体本构关系的特点，建立了适用于宾汉流体的修正动量方程和Ｋτ－ετ模型方程。采用压力耦合半隐式ＳＩＭＰＬＥ算法，通过流场的数值计算研究，指出了宾汉流体本身的物性参数（如屈服应力、塑性粘度）对其湍流强度有着重要影响。
In the paper, a turbulence model k τ ε τ of Bingham fluid is presented according to Bingham fluid constitution equation. With semi implicit method for pressure linked equations, the numerical computations are worked out for Bingham fluid. Material parameters of Bingham fluid (yield stress and plastic viscosity) have an important influence upon turbulence.
