Abstract: High order methods are known to be unstable when applied to nonlinear conservation laws whose solutions exhibit shocks and turbulence. These methods have traditionally required additional filtering, limiting, or artificial viscosity to avoid solution blow up. Entropy stableschemes address this instability by ensuring that physically relevant solutions satisfy a semi-discrete entropy inequality independently of numerical resolution. In this talk, we will review different approaches for constructing entropy stable discontinuous Galerkin
Biosketch: Dr. Chan earned his PhD degree from UT Austin in 2013. He served as a Pfieffer postdoctoral instructor at Rice University from 2013-2015, and as a postdoctoral researcher at Virginia Tech from 2015-2016 before returning to Rice as faculty in 2016. He was a recipient of an NSF CAREER Award (2020). His research focuses on accurate and efficient numerical solutions of time-dependent PDEs. His recent work has focused on the construction of provably stable high order methods for wave propagation and fluid dynamics and their implementation on Graphics Processing Units (GPUs).
