Abstract

Direct numerical simulation of turbulent channel flow is employed to show that two-way coupling effects in particle-laden flows leads to reduced preferential clustering and turbophoresis (Kuerten and Vreman, 2005) even for low values of volume and mass fraction. The effect of including two-way coupling on the phenomenon of turbophoresis and preferential clustering is studied for particles of different response times at a variety of loading ratios.
