Abstract:
This paper deals with the results of implementation of k-kL-ω RANS turbulence model for compressible transitional flow into OpenFOAM. This model was firstly proposed by Walters and Leylek (2005) and utilizes the approach of laminar kinetic energy in order to predict transition between laminar and turbulent flows. The capability of laminar/turbulent transition modelling is tested for the basic flat plate test cases and for the VKI turbine cascade. The comparison between new implementation, k-kL-ω for incompressible flow supplied in OpenFOAM and γ - Reθ model from commercial CFD package FINE/Turbo distributed by NUMECA Int. are shown. The properties of the implementation of k-kL-ω model for compressible flow simulations into OpenFOAM are discussed.
