Stochastic turbulence modeling in RANS simulations via Multilevel Monte Carlo
Prashant Kumar, Martin Schmelzer, Richard P. Dwight
A multilevel Monte Carlo (MLMC) method for quantifying model-form uncertainties associated with the Reynolds-Averaged Navier-Stokes (RANS) simulations is presented. Two, high-dimen…

Data-Driven Modelling of the Reynolds Stress Tensor using Random Forests with Invariance
Mikael L. A. Kaandorp, Richard P. Dwight
A novel machine learning algorithm is presented, serving as a data-driven turbulence modeling tool for Reynolds Averaged Navier-Stokes (RANS) simulations. This machine learning alg…
