Turbulence modification by particles in a backward-facing step flow
John R. Fessler,John K. Eaton +1 more
TL;DR: In this article, a backward-facing step flow with a fully developed channel flow inlet was investigated, and the authors measured gas-phase velocities in the presence of 3-40% mass loadings of three different particle classes (90 and 150 μm diameter glass and 70 μmiameter copper spheres) and found that the level of attenuation decreased with decreasing particle Stokes number, particle Reynolds number and mass loading.
