PINN(s): Physics-Informed Neural Network(s) for von Karman vortex street
This is an implementation of PINN(s) on TensorFlow 2 to learn the flow field of von Karman vortex street, and estimate the fluid density and kinemetic viscosity.
to run the entire code in
directory. This will load data in
and starts training to estimate the fluid density (rho), and kinematic viscosity (nu). Basic parameters (e.g., network architecture, batch size, initializer, etc.) are found in
and could be modified depending on the problem setup.
