A fixed coarse-grid thermal-fluid scheme and a heat conduction scheme in the distinct element method

摘要

A particle-thermal-fluid coupling scheme with a mixed Lagrangian-Eulerian approach is described by extending the author's previous research (Shimizu, 2004). The scheme solves the continuity, Navier-Stokes (N-S) and thermal energy equations numerically in Eulerian Cartesian coordinates by considering the existence of particles within the" cell. On the other hand, in the Distinct Element Method (DEM), driving forces and thermal energy applies to the particles.
