Numerical Simulation of Sand Ripple Formation with Periodically Uniform and Non-Uniform Stream Field

Abstract:

In this study, for the numerical simulation of the sand ripple’s forming process which caused by the sand flow, the simulation models based on the fluid dynamics and the sand flow field by the wind are analyzed. Due to sand field’s characteristics is very complex, the establishing process of stream flow field constitutive equations analyzed at first, and then the implication relations and independency between stream flow field and the sand flow field analyzed. Finally, the sand ripple forming and moving process simulated in uniform and non-uniform stream flow field.
