报告摘要：Recently, neural network-based deep learning methods, which are different from the classical numerical methods, have attracted lots of attention not only in the traditional artificial intelligence but also the scientific computing. In this talk, I will introduce my work using physics-informed neural networks (PINNs) and neural operator learning-based deep multi-scale multi-physics nets (DeepMMnet) for complex fluid with partial or scarce data. In particular, I shall solve the inverse problems of the shock wave problems in supersonic flow by using PINNs based on the information of density gradient ∇ρ and limited data of pressure and inflow conditions instead of using boundary conditions. Then I will introduce the inference of the flow past a normal shock in hypersonic flow by using the DeepMMnets with the help of deep neural operator networks (DeepOnets).
