A nested hybridizable discontinuous Galerkin method for computing second-harmonic generation in three-dimensional metallic nanostructures
Ferran Vidal-Codina, Ngoc-Cuong Nguyen, Cristian Ciraci +2
In this paper, we develop a nested hybridizable discontinuous Galerkin (HDG) method to numerically solve the Maxwell's equations coupled with the hydrodynamic model for the conduct…
Impact of surface roughness in nanogap plasmonic systems
Cristian Ciracì, Ferran Vidal-Codina, Daehan Yoo +3
Recent results have shown unprecedented control over separation distances between two metallic elements hundreds of nanometers in size, underlying the effects of free-electron nonl…
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…
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…
