Abstract

A parametric study has been undertaken using direct numerical simulations (DNS) of forced compressible particle-laden flow in order to determine the validity of the comparison between experimental PIV/PTV flow fields and numerical LES Reynolds/Favre filtered flow fields. This requires solving the 3D Navier-Stokes equations and particle dynamics in a periodic domain where important parameters include the Reynolds number, Mach number, Particle diameter, filter width and ratio of solenoidal to dilatational dissipation. Results of the simulations and a tentative analysis are presented.
