The Development of a Partially Averaged Navier–Stokes KSKL ModelSource: Journal of Fluids Engineering:;2022:;volume( 144 ):;issue: 005::page 51501-1DOI: 10.1115/1.4052484Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new partially averaged Navier–Stokes (PANS) closure is derived based on the k−kL (KSKL) model. The aim of this new model is to incorporate the desirable features of the KSKL model, compared to the k−ω shear stress transport model, into the PANS framework. These features include reduced eddy-viscosity levels, a lower dependency on the cell height at the wall, well-defined boundary conditions, and improved iterative convergence. As well as the new model derivation, the paper demonstrates that these desirable features are indeed maintained, for a range of modeled-to-total turbulence kinetic energy ratios (fk), and even for multiphase flow.
