A review of troubled cell indicators for discontinuous Galerkin method
S R Siva Prasad Kochi, M Ramakrishna
In this paper, eight different troubled cell indicators (shock detectors) are reviewed for the solution of nonlinear hyperbolic conservation laws using discontinuous Galerkin (DG)…
An analytical solution for supersonic flow over a circular cylinder using an optimized shock shape
S R Siva Prasad Kochi, M Ramakrishna
An analytical solution for high supersonic flow over a circular cylinder based on Schneider's inverse method has been presented. In the inverse method, a shock shape is assumed and…
A discontinuous Galerkin overset scheme using WENO reconstruction and subcells for two-dimensional problems
S R Siva Prasad Kochi, M Ramakrishna
A new scheme for communication between overset grids using subcells and Weighted Essentially Non Oscillatory (WENO) reconstruction for two-dimensional problems has been proposed. T…
A compact subcell WENO limiting strategy using immediate neighbors for Runge-Kutta discontinuous Galerkin methods for unstructured meshes
S R Siva Prasad Kochi, M Ramakrishna
In this paper, we generalize the compact subcell weighted essentially non oscillatory (CSWENO) limiting strategy for Runge-Kutta discontinuous Galerkin method developed recently by…
