End-to-end modeling of laminar-turbulent transition


Traditional methods of transition prediction cannot be easily extended to flow configurations where the transition process depends on a large set of parameters. Proposed model uses convolutional neural network and sequence-to-sequence mapping to predict transition in a physically-consistent manner, for a variety of instability mechanisms.
