Numerical analysis of Mud flow using VOF scheme with Non-Newtonian model

Abstract

The behavior of high concentration sediment flow was examined as incompressible viscosity free surface fluid with a pseudo-plastic non-Newton fluid model, and the validity is verified by accuracy verification by experiment. The dam break experiment is conducted with various water content ratios, and the fluid-analysis result and experimental result by the VOF method are compared. Correlations between water content ratio and the dynamic viscosity in N-S equation was examined. The result can reproduce the almost same form and it is thought that the correlation between dynamic viscosity and moisture content can be examined.
