Navier-Stokes simulation of transonic vortex flow over a delta wing
Abstract
An explicit multi-stage Runge-Kutta time-stepping scheme with cell-centered finite volume spatial discretization is employed to solve three-dimensional, compressible Navier-Stokes equations. A novel variation for computation of viscous fluxes is used. Convergence to steady state is expedited through acceleration techniques. The vortex flow over a 65 degree cropped rounded leading edge delta wing is computed, and the results are compared with experimental data and Euler solution.
