Numerical analysis of gas-particle two-phase wake flow by vortex method

The two-dimensional wake gas flows behind a flat plate, loaded with solid particles of the Stokes number 0.15 and 1.4, are simulated through the vortex method proposed by the authors in a prior study. The simulated particle distribution is confirmed to agree with the experimentally visualized result...

Zusammenfassung:The two-dimensional wake gas flows behind a flat plate, loaded with solid particles of the Stokes number 0.15 and 1.4, are simulated through the vortex method proposed by the authors in a prior study. The simulated particle distribution is confirmed to agree with the experimentally visualized result. The simulation clarifies that the loaded particles make the gas mean velocity gradient in the wake cross-section gentler and that the gas turbulent intensity reduces by the particle except near the wake centerline.
