Heat transfer in particle-laden wall-bounded turbulent flows

Abstract

In present work heat transfer in particle-laden wall-bounded turbulent flows has been study with the fluid-particle one way interaction approach. Direct Numerical Simulation of the flow, combined with Lagrangian particle tracking technique has been performed to study the problem. In presented configuration small solid and dense particles carrying by fluid forces are influence by turbulent non-isothermal flow. Numerical computation was performed for various grids for Reynolds number 180, 395 and the molecular Prandtl number 1.0. The effect of particle diameter and density as well as the effect of the Reynolds and Prandtl number on the statistical quantities was examined. The flow field, spatial pattern of particle concentration and particle temperature were presented. It has been shown that particles finally were distributed not uniformly nor hydrodynamic nor thermally.Applied Science
