Abstract
A parametric study has been undertaken using direct numerical simulations (DNS) of forced compressible particleladen flow in order to determine the validity of the comparison between PIV flow fields and 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. Tentative results of the simulations are presented.
