Wall-modeled large-eddy simulation based on building-block flows
Yuenong Ling, Gonzalo Arranz, Emily Williams +3
A unified subgrid-scale (SGS) and wall model for large-eddy simulation (LES) is proposed by devising the flow as a collection of building blocks that enables the prediction of the…
Multi-agent reinforcement learning for wall modeling in LES of flow over periodic hills
Di Zhou, Michael P. Whitmore, Kevin P. Griffin +1
We develop a wall model for large-eddy simulation (LES) that takes into account various pressure-gradient effects using multi-agent reinforcement learning (MARL). The model is trai…
Compressible Velocity Transformations for Various Noncanonical Wall-Bounded Turbulent Flows
Tianyi Bai, Kevin P. Griffin, Lin Fu
This work assesses several popular transformations for the velocity profile through their application to several types of non-canonical compressible wall-bounded turbulent flows. S…
Non-Boussinesq subgrid-scale model with dynamic tensorial coefficients
Rahul Agrawal, Michael P. Whitmore, Kevin P. Griffin +2
A major drawback of Boussinesq-type subgrid-scale stress models used in large-eddy simulations is the inherent assumption of alignment between large-scale strain rates and filtered…
