 Abstract

Particle impaction on a cylinder in a cross flow is investigated with the use of Direct Numerical Simulations (DNS), with a focus on the effect of turbulence on the impaction efficiency. It is found that for particles with Stokes numbers in the boundary stopping mode there is up to ten times more front side impaction for turbulence with a large integral scale, than for a corresponding laminar flow. The back side impaction efficiency is also found to be influenced by the turbulence. The highest back side impaction efficiency is found for turbulence with small integral scales.
