摘要

Simulation of sediment transport in turbulent channel flows is of vital interest in various applications such as environmental or biomedical flows. While the interaction of the fluid and the particle can be tackled numerically using a phase-resolved immersed boundary method (IBM), the particle-particle interaction has to be modeled using an appropriate collision model. This paper presents a sensitivity analysis for the particle-laden flow in a turbulent channel with respect to the type of collision model employed.
