recommendations! Published in 2021 at "Journal of Fluid Mechanics"

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.
