The application of laminar kinetic energy to laminarturbulent transition prediction
RESUMO
This paper presents the initial steps taken in order to determine the most effective method to predict flows in a transitional regime, which can then be applied to the rear wing of a Formula 1 vehicle. Recent literature [1][2] suggests that incorporation of laminar kinetic energy is a promising method of transition prediction for industrial requirements. Two models incorporating laminar kinetic energy are implemented in an industrial finite volume code for validation and to investigate possible improvements for the final application. Additionally, several low-Reynolds number eddy-viscosity models are tested for a flat plate subjected to a turbulence intensity sufficiently high for bypass transition. The skin-friction coefficients are compared with experimental results and the fully turbulent profiles are examined. Although the physics of laminar kinetic energy are not completely understood at present, the results suggest that the modeling of it simulates additional physics within a boundary layer. The work is ongoing.
