Abstract

In this paper the peridynamics theory is integrated with a DEM-IB-CLBM (Discrete Element-Immersed Boundary-Cascaded Lattice Boltzmann Method) framework to enable fully-resolved simulations of sand erosion in viscous fluids. The crack and damage of the material walls are modelled with the peridynamics theory, the no-slip boundary condition is implemented on the surface of particles using an Immersed Boundary Method (IBM) and particle collisions are accurately resolved using a Discrete Element Method. The method is validated by comparing the trajectory of a particle colliding with a wall in a viscous fluid with the previous results provided in the literature. The impact of the generated craters due to the collisions on the vortex field and also the impact of collision angle on the material damage are investigated.
