DOI: 10.1017/jfm.2021.172
Abstract: Abstract High-speed boundary-layer transition is extremely sensitive to the free-stream disturbances which are often uncertain. This uncertainty compromises predictions of models and simulations. To enhance the fidelity of simulations, we directly infuse them with available… read more here.
