摘要

使用CFD软件对泥石流中固体物质以土为主的Bingham型黏性泥石流流体进行了三维数值模拟.首先通过CAD软件AutoCAD和Unigraphics

建立了泥石流沟谷三维地形模型

然后分析了泥石流流体的流变特性

并建立了Bingham计算模型

最后运用CFD软件CFX

对泥石流流体的速度场及压力场的大小与分布进行了三维数值模拟分析

得出了流场的相关力学指标和泥石流速度场及压力场的大小与分布

并实现了泥石流模拟结果的显示.计算结果表明

泥石流流体数值模拟可以在CFD软件环境下完成

计算得出的泥石流流场各种数据有助于更合理地避让和防治泥石流.

Abstract

The CFD software was used to simulate the flow field of Bingham viscous debris flow which mainly consists of soil in solid matter. A 3-D land model of debris flow was established with CAD software AutoCAD/Unigraphics(UG). By analyzing the rheological character of debris flow fluid

a Bingham computational model was built up. The CFD software CFX was used to simulate 3-D distributions of velocity and pressure fields of debris flow

and the results were expressed via the section of CFX-Post. It is concluded that numerical simulation of debris flow fluid can be performed with CFD software to practically evade and control debris flow.
