Efficient Hybrid WENO Schemes for Special Relativistic Hydrodynamics with Adaptive Characteristic Reconstruction
Rakesh Kumar, Biswarup Biswas, Asha Kumari Meena +1
Special relativistic hydrodynamics (SRHD) equations arise in the modeling of high-speed fluid flows encountered in astrophysical phenomena such as jets, supernova explosions, and g…

Positivity-preserving finite difference WENO scheme for Ten-Moment equations with source term
Asha Kumari Meena, Rakesh Kumar, Praveen Chandrashekar
We develop a positivity-preserving finite difference WENO scheme for the Ten-Moment equations with body forces acting as a source in the momentum and energy equations. A positive f…

A path conservative finite volume method for a shear shallow water model
Praveen Chandrashekar, Boniface Nkonga, Asha Kumari Meena +1
The shear shallow water model provides an approximation for shallow water flows by including the effect of vertical shear in the model. This model can be derived from the depth ave…
