Application in soil erosion studying based on CFD numerical simulation method

Based on the analysis of coal-ash average infiltration rate with different density and different mixed ratio with soil by applying CFD numerical simulation method, and comparison with actual data of the document, the results showed that: coal-ash average infiltration rate is inversed with the sample density in the experiment. At the same time, the curvature of curve fitting varied with different average infiltration rate. The curvature expanded with the increase of the average infiltration rate and mixed ratio. It is possible to apply CFD numerical simulation method in analysis of soil water erosion. The way is applicable for soil and wind erosion by the result of document. In view of being economical, high-efficient, and swift to the CFD numerical simulation, the method is to be of great practical prospect in the soil erosion. It provides a new kind of thought in the soil erosion studies especially in the future studies of the soil erosion occurrence mechanism.
