An advanced heat transfer model for Eulerian-Lagrangian simulations of industrial gas-solid flow systems
Toshiki Imatani, Mikio Sakai
The discrete element method (DEM) coupled with computational fluid dynamics (CFD), has been developed to simulate complex solid-fluid flow systems. Today, DEM is regarded as an est…
