In both regimes, the high-wavenumber content of turbu-lence is shown to be significantly impacted due to deposition of thermal energy.

Subgrid-scale modeling for large eddy simulations has been an integral theme of most research groups, and the particle-laden flows group has not been an exception to this rule. Particle-laden flows refers to a class of two-phase fluid flow, in which one of the phases is continuously connected (referred to as the continuous or carrier phase) and the other phase is made up of small, immiscible, and typically dilute particles (referred to as the dispersed or particle phase).Fine aerosol particles in air is an example of a particle-laden flow; the aerosols are the.

Understanding how shock waves, flow dynamics and turbulence all interact and affect the distribution of particles has applications ranging from high-speed vehicles to explosions and even ocean sediment dynamics.

Introduction. Modeling the two phase flow involving multiple metallic particles moving at high speeds in high speed compressible flow must account for the fluid induced forces acting on the particles, the effects of the particle motion and their presence on the flow conditions, and the interactions between the particles or other objects as they by: 7.

The investigations on particle-laden gas flows around a sphere can be found in Schuch and Löffler [13], Varaksin [14] and Ho [15]. In such flows, the impact efficiency η is defined as the ratio.

In this work we study the numerical simulation of particle-laden fluids, with an emphasis on Newtonian fluids and spherical, rigid particles. Our general strategy consists in using the discrete element method (DEM) to model the particles and the finite element method (FEM) to discretize the continuous phase, such that the fluid is not resolved around the particles, but rather averaged over by: 1.
