An End-to-End PyTorch Interface for Differentiable PDE Solvers: A RANS Model-Correction Study
Luca Saverio, Michele Alessandro Bucci, Gianmarco Farro +2
This work presents an end-to-end strategy for solving inverse problems constrained by Partial Differential Equations within a fully differentiable Machine Learning framework. The p…
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…
Projection method for mean resolvent analysis of periodic flows
Alessandro Bongarzone, Cédric Content, Denis Sipp +1
The mean resolvent operator predicts the mean linear response to forcing in the frequency domain and provides the optimal linear time-invariant approximation of statistically stead…
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…
Transition mechanisms in hypersonic wind-tunnel nozzles: a methodological approach using global linear stability analysis
Hugo Lemarquand, Mathieu Lugrin, Cédric Content +3
Base-flow computations and stability analyses are performed for a hypersonic wind tunnel nozzle at a Mach number of 6. Isothermal and adiabatic wall boundary conditions are investi…
