The modeling technology envisaged is one based on coupling a combined finite-discrete element (FEM-DEM) solids model with a generic multi-fluids model (Fluidity). Progress towards the study of instability and breakage as wave energy creates turbulence, block movement, and internal stresses is ...
With the increase in computation power and algorithm efficiency, numerical methods have now reached the level where they can be used in this development process.Erik VroegrijkProceedings of the 14th numerical towing tank symposium: 22nd‐24th October 2011, Poole, England...
The simulation of a 3-dimentional gas and particle two-phase flow in the FEM has been carried out for the first time in this work by coupling the CFD and DEM. As the operating pressures increase, the kinetic energy of particles increases, and consequently the collisions between the particle ...
