Point-Particle DNS and LES of Particle-Laden Turbulent flow - a state-of-the-art review

Particle-laden or droplet-laden turbulent flows occur in many industrial applications and in natural phenomena. Knowledge about the properties of these flows can help to improve the design of unit operations in industry and to predict for instance the occurrence of rain showers. This knowledge can be obtained from experimental research and from numerical simulations. In this paper a review is g...

Direct Numerical Simulation of Particle-Laden Homogeneous Isotropic Turbulent Flows Using a Two-Fluid Model Formulation

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...

Decoupling The Role Of Inertia And Gravity On Particle Dispersion

Turbulent gas flows laden with small, dense particles are encountered in a wide number of important applications in both industrial settings and aerodynamics applications. Particle interactions with the underlying turbulent flow are exceedingly complex and, consequently, difficult to accurately model. The difficulty arises primarily due to the fact that response of a particle to the local envir...

Towards Large Eddy Simulation of Non-Homogeneous Particle Laden Turbulent Gas Flows Using Euler-Euler Approach

A Large Eddy Simulation approach for Eulerian-Eulerian dispersed two-phase flow is presented. It is shown that not only a Sub-Grid Scales term modeling the unresolved field in the mesoscopic momentum transport equation of the dispersed phase, but also a stress term modeling the Random-Uncorrelated Motion is needed. Simulations of a non-homogeneous particle laden turbulent gas flow allow to comp...
