Optimal non-linear mechanisms for laminar-turbulent transition of a shock-induced separated shear layer
Flavio Savarino, Denis Sipp, Georgios Rigas
Laminar-turbulent transition in shock wave-boundary-layer interactions (SWBLI) remains a major challenge for hypersonic vehicle design, with implications for drag, heat transfer, a…

Optimal transitional mechanisms of incompressible separated shear layers subject to external disturbances
Flavio Savarino, Denis Sipp, Georgios Rigas
Optimal transitional mechanisms are analysed for an incompressible shear layer developing over a short, pressure gradient-induced laminar separation bubble (LSB) with peak reversed…

Mori-Zwanzig latent space Koopman closure for nonlinear autoencoder
Priyam Gupta, Peter J. Schmid, Denis Sipp +2
The Koopman operator presents an attractive approach to achieve global linearization of nonlinear systems, making it a valuable method for simplifying the understanding of complex…
