研究簡介

Dr. Elling's research interests are in partial differential equations 
 modelling fluid dynamics. His past work focuses on shock reflection,
 in particular weak-strong selection and regular-Mach transition, 
 on non-uniqueness and the carbuncle phenomenon, and more recently 
 on existence of vortex spirals in incompressible flow.
