Abstract: 

In this presentation, I would like to demonstrate the effectiveness of PINNs in solving several inverse heat transfer problems. To justify its effectiveness, the time taken by PINNs to solve the entire problem is compared with the time taken by COMSOL Multiphysics Software (FEM approach) to solve the forward problem once. Steady and unsteady problems governed by both linear and nonlinear PDEs have been chosen as the test cases, to check if PINNs can handle a variety of problems often encountered in the field of heat transfer. I will conclude after mentioning a specific type of PINN architecture that works very well for PDEs that are highly nonlinear.
