Physically constrained eigenspace perturbation for turbulence model uncertainty estimation
Marcel Matha, Christian Morsbach
Aerospace design is increasingly incorporating Design Under Uncertainty based approaches to lead to more robust and reliable optimal designs. These approaches require dependable es…
Physics-constrained Random Forests for Turbulence Model Uncertainty Estimation
Marcel Matha, Christian Morsbach
To achieve virtual certification for industrial design, quantifying the uncertainties in simulation-driven processes is crucial. We discuss a physics-constrained approach to accoun…
Large eddy simulation of a low-pressure turbine cascade with turbulent end wall boundary layers
Christian Morsbach, Michael Bergmann, Adem Tosun +3
We present results of implicit large eddy simulation (LES) and different Reynolds-averaged Navier-Stokes (RANS) models of the MTU 161 low pressure turbine at an exit Reynolds numbe…
Improved self-consistency of the Reynolds stress tensor eigenspace perturbation for uncertainty quantification
Marcel Matha, Christian Morsbach
The limitations of turbulence closure models in the context of Reynolds-averaged NavierStokes (RANS) simulations play a significant part in contributing to the uncertainty of Compu…
