Influence of Particle-Wall Interaction Modeling on Particle Dynamics in Near-Wall Regions of Turbulent Channel Down-Flow

Part of the ERCOFTAC Series book series (ERCO, volume 15)

Abstract

Particle-laden channel flows are found in a variety of natural settings and are also of great practical importance due to their frequent occurrence in engineering applications. Numerous experimental and computational studies related to particle transport in turbulent flows were reported in the literature. There have been a few applications of Direct Numerical Simulations to particle-laden channel flows, such as in (Li et al., 2001) and (Soltani and Ahmadi, 1995). Those studies necessarily focus on rather low Reynolds numbers. Kulick et al. (1994) reported results of experiments on particle-laden flows in a vertical channel down-flow at Re τ ≈644 (based on friction velocity and channel half-width). Large-Eddy Simulation results for a channel flow at approximately the same Reynolds number are also available, e.g. (Fukagata et al., 2001).
