Implicit gradients based novel finite volume scheme for compressible single and multi-component flows
Amareshwara Sainadh Chamarthi, Steven H. Frankel, Abhishek Chintagunta
This paper introduces a novel approach to compute the numerical fluxes at the cell boundaries in the finite volume approach. Explicit gradients used in deriving the reconstruction…
High-Order Central-Upwind shock capturing scheme using a Boundary Variation Diminishing (BVD) Algorithm
Amareshwara Sainadh Chamarthi, Steven Frankel
In this paper, we present a novel hybrid nonlinear explicit-compact scheme for shock-capturing based on a boundary variation diminishing (BVD) reconstruction. In our approach, we c…
First order hyperbolic approach for Anisotropic Diffusion equation
Amareshwara Sainadh Chamarthi, Hiroaki Nishikawa, Kimiya Komurasaki
In this paper, we present a high order finite difference solver for anisotropic diffusion problems based on the first-order hyperbolic system method. In particular, we demonstrate…
High-order upwind and non-oscillatory approach for steady state diffusion, advection-diffusion and application to magnetized electrons
Amareshwara Sainadh Chamarthi, Kimiya Komurasaki, Rei Kawashima
Steady state simulations} of magnetized electron fluid equations with strong anisotropic diffusion based on the first-order hyperbolic approach is carried out using cell-centered h…
