Calculation of a turbulent boundary layer on a flat plate using the PAFV-ω turbulence model

Abstract To advance the creation of more efficient turbulence models and enhance the precision of numerical simulations of turbulent boundary layer flow, in this paper, based on the PAFV turbulence model and K-ω turbulence model, a new PAFV-ω turbulence model is raised, which is used for the computation of compressible fluids and requires only one empirical coefficient. A novel turbulence model was developed and numerically simulated for turbulent boundary layer flow without pressure gradient on a flat plate using the OpenFOAM software platform. Distribution patterns of mean velocity and transversely averaged fluctuating velocity are obtained. In addition, the logarithmic rate of the turbulent boundary layer is investigated. The differences between the calculated values of the drag coefficients and the experimental results are analyzed. The results show that the numerical calculation results of the flat-panel turbulent boundary layer flow using the PAFV-ω turbulence model are in good agreement with the theoretical values. The applicability of the PAFV-ω turbulence model for calculating the flatplate turbulent boundary layer flow is preliminarily verified.
