Abstract
Higher order discretization on unstructured grids can be a possible avenue for improving the predictive capabilities of numerical flow simulations. Therefore, a two dimensional Navier Stokes flow solver on unstructured quadrilateral grids has been developed, associated with an elliptic structured grid generation module. This solver is based on the higher order Spectral Difference method for spatial discretization. The solver is tested for validity with the published data and the expected order of accuracy of the method is also achieved
