Kemna, Maarten (author), Heinlein, A. (author), Vuik, Cornelis (author)Surrogate models based on convolutional neural networks (CNNs) for computational fluid dynamics (CFD) simulations are investigated. In particular, the flow field inside two-dimensional channels with a sudden expansion and an obstacle is predicted using an image representation of the geometry as the input. Generative adversarial neural networks ...journal article 2023
