Entropy stable numerical schemes for divergence diminishing Chew, Goldberger & Low equations for plasma flows
Chetan Singh, Harish Kumar, Deepak Bhoriya +1
Chew, Goldberger & Low (CGL) equations are a set of hyperbolic PDEs with non-conservative products used to model the plasma flows, when the assumption of local thermodynamic equili…
An Alternative Finite Difference WENO-like Scheme with Physical Constraint Preservation for Divergence-Preserving Hyperbolic Systems
Dinshaw S. Balsara, Deepak Bhoriya, Chi-Wang Shu
Alternative finite difference Weighted Essentially Non-Oscillatory (AFD-WENO) schemes allow us to very efficiently update hyperbolic systems even in complex geometries. Recent inno…
Physical Constraint Preserving Higher Order Finite Volume Schemes for Divergence-Free Astrophysical MHD and RMHD
Dinshaw S. Balsara, Deepak Bhoriya, Chetan Singh +3
Higher order finite volume schemes for magnetohydrodynamics (MHD) and relativistic magnetohydrodynamics (RMHD) are very valuable because they allow us to carry out astrophysical si…
Chew, Goldberger & Low Equations: Eigensystem Analysis and Applications to One-Dimensional Test Problems
Chetan Singh, Deepak Bhoriya, Anshu Yadav +2
Chew, Goldberger & Low (CGL) equations describe one of the simplest plasma flow models that allow anisotropic pressure, i.e., pressure is modeled using a symmetric tensor described…
Second order divergence constraint preserving schemes for two-fluid relativistic plasma flow equations
Jaya Agnihotri, Deepak Bhoriya, Harish Kumar +2
Two-fluid relativistic plasma flow equations combine the equations of relativistic hydrodynamics with Maxwell's equations for electromagnetic fields, which involve divergence const…
An anisotropic plasma model of the heliospheric interface
Vladimir Florinski, Dinshaw S. Balsara, Deepak Bhoriya +4
We present a pioneering model of the interaction between the solar wind and the surrounding interstellar medium that includes the possibility of different pressures in directions p…
