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…
Entropy-stable hybridized discontinuous Galerkin methods for the compressible Euler and Navier-Stokes equations
Pablo Fernandez, Ngoc-Cuong Nguyen, Jaime Peraire
In the spirit of making high-order discontinuous Galerkin (DG) methods more competitive, researchers have developed the hybridized DG methods, a class of discontinuous Galerkin met…
Hybridized discontinuous Galerkin methods for wave propagation
Pablo Fernandez, Alexandra Christophe, Sebastien Terrana +2
We present the recent development of hybridizable and embedded discontinuous Galerkin (DG) methods for wave propagation problems in fluids, solids, and electromagnetism. In each of…
A physics-based shock capturing method for large-eddy simulation
Pablo Fernandez, Ngoc-Cuong Nguyen, Jaime Peraire
We present a shock capturing method for large-eddy simulation of turbulent flows. The proposed method relies on physical mechanisms to resolve and smooth sharp unresolved flow feat…
Non-modal analysis of spectral element methods: Towards accurate and robust large-eddy simulations
Pablo Fernandez, Rodrigo Moura, Gianmarco Mengaldo +1
We introduce a \textit{non-modal} analysis technique that characterizes the diffusion properties of spectral element methods for linear convection-diffusion systems. While strictly…
