Abstract
A cell-centered density-based finite volume Euler/Navier-Stokes flow solver is developed in this study. The calculation of the inviscid fluxes is based on Roe’s approximate Riemann solver. To achieve second order spatial accuracy, the piecewise linear reconstruction approach is used. Two methods are used to compute the gradients, and a discussion of the viscous fluxes is presented. For temporal integration, both explicit and implicit methods are implemented. A brief description of the parallelization strategy is also included. For turbulent flow computations, the Spalart-Allmaras one-equation turbulence model is adopted. Several validation cases are presented, and the computed results show good agreement with the experimental and theoretical data.
