Title:
Numerical investigation of minimum drag profiles in laminar flow using deep learning surrogates 
Abstract:
Efficiently predicting the flow field and load in aerodynamic shape optimisation remains a highly challenging and relevant task. Deep learning methods have been of particular interest for such problems due to their success in solving inverse problems in other fields. In the present study U-net-based deep neural network (DNN) models are trained with high-fidelity datasets to infer flow fields and then employed as surrogate models to carry out the shape optimisation problem i.e.To find a minimal d...    »
