A numerical method is developed to solve the Navier-Stokes equations for laminar compressible flow around delta wings. A large-scale solution on a mesh of 129 x 49 x 65 points for transonic flow Moo = 0.85, a = 10 deg, and Re*>,cR = 2.38 X 10 around a 65 deg swept delta wing with round leading edge is presented and discussed. The results reveal the presence of primary, secondary, and even tertiary vortices. Comparison with experiment shows that the interaction between the primary and secondary vortices is obtained correctly and that these results are a more realistic simulation than the one given by the Euler equations.
