Stochastic Diffusion of Finite Inertia Particles in Non-Homogeneous Turbulence particles were injected near the wall (..=4) of a turbulent boundary layer that is strongly anisotropic and inhomogeneous near the wall. To assess the performance of the models for wide range of particle inertias (Stroke numbers), the CRW results were compared to particle diffusion statistics gathe

Fluctuating Immersed Material (FIMAT) Dynamics for the Direct Simulation of the Brownian Motion of P presented. In this approach the thermal fluctuations are included in the fluid equations via random stress terms. Solving the fluctuating hydrodynamic equations coupled with the particle equations of motion results in the Brownian motion of the particles. There is no need to add a random force term

DNS of Collective Behavior of Solid Particles in a Homogeneous Fieldcles was directly simulated. Since flow around each particle is approximately resolved, no models were used for particle motion or fluid turbulence. A particle settles under gravity with the Reynolds number ranging from 50 to 300, based on diameter and slip velocity. When particle clusters are forme

—A New Computational Scheme for Deformable Particles and Particle Interaction Problemsomputational method, it is very flexible and it appears to be ideal in solving fluid-particle interaction problems including problems with deformable boundaries. Proteus uses a regular Eulerian grid for the flow domain and a regular Lagrangian grid to follow particles that are contained in the flow

Turbulence Modulation by Micro-Particles in Boundary Layersentration is modified due to the action of particles themselves in modulating turbulence. The physical mechanisms and the statistics proposed are based on Direct Numerical Simulation (DNS) of turbulence and Lagrangian particle tracking, considering a two-way coupling between particles and fluid.
