Fast and Accurate Proper Orthogonal Decomposition using Efficient Sampling and Iterative Techniques for Singular Value Decomposition
Charumathi V, M. Ramakrishna, Vinita Vasudevan
In this paper, we propose a computationally efficient iterative algorithm for proper orthogonal decomposition (POD) using random sampling based techniques. In this algorithm, addit…
Addressing the issue of mass conservation error and the connected problem of Carbuncle formation
Vinnakota Mythreya, K. S. R. Siva Prasad., M. Ramakrishna
We study mass conservation errors (momentum density spike) and the related phenomenon of post shock oscillations in numerical solutions of compressible Euler equations. These pheno…
Shock capturing with discontinuous Galerkin Method using Overset grids for two-dimensional Euler equations
S R Siva Prasad Kochi, M Ramakrishna
A new procedure to capture the shocks has been proposed and is demonstrated for the solutions of two-dimensional Euler equations using discontinuous Galerkin method and overset gri…
