Well-posedness of neural turbulence closures and tangent dissipation

Zhen Zhang, George Em Karniadakis

A neural turbulence closure defines a new boundary-value problem, $R (U) = N (U) + F (U) = 0$ , with a coupled Jacobian $J (U) = N^{'} (U) + F^{'} (U)$ , where $N$ is the original mean-flow operator and $…

Effect of Turbulence-Closure Consistency on Airfoil Identification

Zhen Zhang, George Em Karniadakis

We consider an inverse flow problem in which the airfoil shape is identified from its wake signature, namely the velocity field in the wake of a target airfoil. This is an ill-pose…
