Abstract A DNS approach for Eulerian-Eulerian dispersed particles simulation is presented in which a stress term corresponding to the uncorrelated motion of dispersed particles is identified. Two models for this stress terms are proposed. The first model uses an isentropic approximation that relates the local amount of uncorrelated particle kinetic energy to the particle number density. The sec...
