Direct Numerical Simulation of Turbulent Channel Flow with Particles

A direct numerical simulation (DNS) of a turbulent channel flow with a Reynolds number of 360 (based on channel height and friction velocity) has been performed. Particles with dimensionless response times of 10, 100 and 200 were introduced in the flow. For each particle type 30,000 particles were tracked for a number of eddy turnover times. The computed particle statistics are compared with the solution of Swailes and Reeks (1994) of the kinetic equation proposed by Reeks (1990) as a model for this flow.
