Abstract

The vortex flow over a round leading-edge delta wing is presently computed by means of a three-dimensional, laminar, thin-layer Navier-Stokes solver which employs finite volume spatial discretization and Runge-Kutta time integration. The results thus obtained are compared with those of experiments and of an Euler simulation. The Navier-Stokes code proceeds on a 64 x 24 x 32 grid of13; 0-0 topology. Flow is computed for a freestream Mach number of 0.85,at 10-deg angle of incidence. Pressure trends and primary and secondary vortices are found to be well predicted.
