Abstract:  We will review physics-informed neural networks (PINNs) and operator regression networks (DeepOnets) with emphasis on discovering missing physics and system identification in diverse applications in fluid mechanics. The diverse problems we consider are ill-posed and cannot be solved with any traditional methods. For example, we can obtain the drag and lift forces on bluff bodies from smoke visualizations or quantify the 3D velocity and pressure fields over an espresso cup based on Schlieren photography
