An asymptotic preserving scheme satisfying entropy stability for the barotropic Euler system
Megala Anandan, Mária Lukáčová-Medvid'ová, S. V. Raghurama Rao
In this paper we study structure-preserving numerical methods for low Mach number barotropic Euler equations. Besides their asymptotic preserving properties that are crucial in ord…
Entropy conserving/stable schemes for a vector-kinetic model of hyperbolic systems
Megala Anandan, S. V. Raghurama Rao
The moment of entropy equation for vector-BGK model results in the entropy equation for macroscopic model. However, this is usually not the case in numerical methods because the cu…
An upwind method for genuine weakly hyperbolic systems
Naveen Kumar Garg, Michael Junk, S. V. Raghurama Rao +1
In this article, we attempted to develop an upwind scheme based on Flux Difference Splitting using Jordan canonical forms to simulate genuine weakly hyperbolic systems. Theory of J…
