Scale-resolving simulations of a circular cylinder subjected to low mach number turbulent inflow

Inflow turbulence is relevant for many engineering applications relating to noise generation, including aircraft wings, landing gears, and non-cavitating marine propellers. While modelling of this phenomenon is well-established for higher Mach number aerospace problems, lower Mach number applications, which include marine propellers, still...

On the accuracy of partially averaged Navier–Stokes resolution estimates

Partially Averaged Navier–Stokes computations can employ three different approaches for specifying the ratio of modelled-to-total turbulence kinetic energy f_k. Use can be made of either a constant, a spatially- or a spatially- and temporally-varying value. This work compares different estimates for f_k found in literature...
