Generation of a Turbulent Boundary Layer Inflow for RANS Simulations

Résumé

The generation of a fully turbulent boundary layer profile is investigated using analytical and numerical methods over the Reynolds number range $300 \leq Re_{\theta} \leq 31000$. The predictions are validated against reference wind tunnel measurements with a zero streamwise pressure gradient. The analytical method is then tested for favourable pressure gradient by modelling the turbulent boundary layer approaching a two-dimensional potential sink. Both methods show a good predictive ability under a zero pressure gradient, with the numerical method providing a complete velocity profile through the laminar sub-layer down to the wall. This work is of practical interest to computational fluid dynamic practitioners for generating an equilibrium thick turbulent boundary layer at the computational domain inflow.
