Three dimensional numerical simulation of Bingham viscous debris flow fluid. (Chinese. English summary) Zbl 1174.76321

Summary: The CFD software is 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 is established with CAD software AutoCAD/Unigraphics (UG). By analyzing the rheological character of debris flow fluid, a Bingham computational model is built up. The CFD software CFX is used to simulate 3-D distributions of velocity and pressure fields of debris flow, and the results are 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.
