In the following we want to give an overview of our recent publications on deep learning methods for solving various aspects of fluid problems modeled with the Navier-Stokes (NS) equations. These topics are a central theme of the research work in our group. While, naturally, the long term goal would be to simply give the initial conditions of a problem as input to a neural network, and then rely on the network to infer the solution with appropriate accuracy, the complexity of the NS equations makes this an extremely challenging problem.
Thus, we typically consider constrained solution spaces for sub-problems of the NS equations, that we believe are nonetheless very interesting, and useful for their respective domains. In this way, we are also working towards improving the state of the art in order to tackle more and more general problems in the future.
Our publications have targeted different aspects of a typical simulation pipeline, and differ in terms of how deeply integrated they are into the NS solve. The following list is order from loose to tight couplings. E.g., the last entry completely replaces a regular NS solve.
