On the ability of discontinuous Galerkin methods to simulate under-resolved turbulent flows
Pablo Fernandez, Ngoc-Cuong Nguyen, Jaime Peraire
We investigate the ability of discontinuous Galerkin (DG) methods to simulate under-resolved turbulent flows in large-eddy simulation. The role of the Riemann solver and the subgri…
Toward a chaotic adjoint for LES
Patrick J. Blonigan, Pablo Fernandez, Scott M. Murman +3
Adjoint-based sensitivity analysis methods are powerful tools for engineers who use flow simulations for design. However, the conventional adjoint method breaks down for scale-reso…
Lyapunov spectrum of separated flows and its dependence on numerical discretization
Pablo Fernandez, Qiqi Wang
We investigate the Lyapunov spectrum of separated flows and their dependence on the numerical discretization. The chaotic flow around the NACA 0012 airfoil at low Reynolds number a…
