Bayesian parameter estimation of a kε model for accurate jetincrossflow simulations
Abstract
Reynoldsaveraged Navier–Stokes models are not very accurate for highReynoldsnumber compressible jetincrossflow interactions. The inaccuracy arises from the use of inappropriate model parameters and modelform errors in the Reynoldsaveraged Navier–Stokes model. In this study, the hypothesis is pursued that Reynoldsaveraged Navier–Stokes predictions can be significantly improved by using parameters inferred from experimental measurements of a supersonic jet interacting with a transonic crossflow.
