Inflow turbulence variables play a key role in the performance of correlation-based transition
models. In order to consider such important effect, results of flat plate and airfoil cases are
simulated using both the Langtry-Menter transition model and the eN model within the
MSES code. Additionally, the use of a turbulence conservation box adapted to the swept
wing in a wing-body configuration is addressed in the paper. The simulations are performed

Inflow turbulence variables play a key role in the performance of correlation-based transition models. In order to consider such important effect, results of flat plate and airfoil cases are simulated using both the Langtry-Menter transition model and the eN model within the MSES code. Additionally, the use of a turbulence conservation box adapted to the swept wing in a wing-body configuration is addressed in the paper. The simulations are performed considering the compressible preconditioned Reynolds-averaged Navier-Stokes equations, which is one of the options offered by the CFD++ finite volume solver. Turbulence closure is achieved with the SST model. The turbulence model is augmented by a transition model based on two additional transport equations, one for the intermittency and another for the momentum thickness Reynolds number.
