Direct numerical simulation of two boundary layers with the same pressure distribution but different surface curvatures
Philippe Spalart, Kenneth Jansen, Gary Coleman
A pair of Direct Numerical Simulations is used to investigate curvature and pressure effects. One has a Gaussian test bump and a straight opposite wall, while the other has a strai…
In Situ Framework for Coupling Simulation and Machine Learning with Application to CFD
Riccardo Balin, Filippo Simini, Cooper Simpson +7
Recent years have seen many successful applications of machine learning (ML) to facilitate fluid dynamic computations. As simulations grow, generating new training datasets for tra…
Turbulent boundary layer with strong favorable pressure gradient and curvature effects: Streamline coordinate and scaling analysis
Aviral Prakash, Riccardo Balin, John A. Evans +1
Direct numerical simulation (DNS) of a turbulent boundary layer over the Gaussian (Boeing) bump is performed. This boundary layer exhibits a series of adverse and favorable pressur…
Invariant Data-Driven Subgrid Stress Modeling on Anisotropic Grids for Large Eddy Simulation
Aviral Prakash, Kenneth E. Jansen, John A. Evans
We present a new approach for constructing data-driven subgrid stress models for large eddy simulation of turbulent flows using anisotropic grids. The key to our approach is a Gali…
Optimal Clipping of Structural Subgrid Stress Closures for Large Eddy Simulation
Aviral Prakash, Kenneth E. Jansen, John A. Evans
Structural subgrid stress models for large eddy simulation often allow for backscatter of energy from unresolved to resolved turbulent scales, but excessive model backscatter can e…
Invariant Data-Driven Subgrid Stress Modeling in the Strain-Rate Eigenframe for Large Eddy Simulation
Aviral Prakash, Kenneth E. Jansen, John A. Evans
We present a new approach for constructing data-driven subgrid stress models for large eddy simulation of turbulent flows. The key to our approach is representation of model input…
