The vortex flow over a 65 degree cropped delta wing with round leading edge, at Minfinity = 0.85 and Reinfinity = 2.38 x 106, has been analyzed for 10 degree, 20 degree, and 30 degree angles of attack. A vertex based finite volume code, JUMBO3D, with an algebraic turbulence model has been used to solve the Reynolds Averaged Navier-Stokes (RANS) equations. An H-O type grid generated by a hybrid elliptic-algebraic method has been used here, and a significant improvement of the results over an O-O type grid has been obtained. The results are compared with available experimental data. The complex physical phenomena due to interactions among the primary, secondary, and tertiary vortices, cross-flow and terminating shocks, and turbulent boundary layer, as visualized from the numerical solutions obtained are presented and discussed here.
