| 摘 要： | 本文以Ｎａｖｉｅｒ－Ｓｔａｋｅｓ方程为基本方程，将泥石流的一种特殊形式－泥流作为Ｂｉｎｇｈａｍ流体，用有限体积法对三种不同底部条件的泥流流场进行了数值模拟，给出了速率分布，并指出了泥流与清水流动的不同之处。

| Abstract: | In this paper, numerical simulations of steady mud flow are presented. Based on Bingham fluid model, the author solved the Navier-Stokes equation by Finite Volume Method. Three velocity profiles were given, corresponding three different bottom boundary conditions in flow field. Finally, the difference between rnud flow and water was pointed out. |
