Abstract
Transition from laminar to turbulent flow plays a significant role in modern aircraft designs. Numerical simulations of flows around flying aircrafts still mostly rely on RANS (Reynolds-averaged Navier-Stokes) approaches which use semi-empirical closures to model turbulent flow. The most general level of RANS closures is achieved by modelling the six individual transport equations of the Reynolds-stress tensor (Reynolds-stress model, RSM). To account for near-wall turbulence effects additional low-Reynolds number damping functions can be applied which locally alter the model calibration.
