Abstract
A model for simulation of flow of suspension of a non-Newtonian fluid and particles of arbitrary shape is briefly introduced and demonstrated on examples of flow of self compacting concrete. The model is based on the lattice Boltzmann method for flow, the immersed boundary method with direct forcing representing the fluid - particle interactions, newly developed algorithm solving the dynamics and interactions of particles and a free surface algorithm based on the mass tracing algorithm. These techniques separating the complex problem into several levels result in a robust and accurate model that allows direct fully coupled simulations of typical laboratory experiments.
