Detailed study of the flows around double‐delta wings is undertaken by performing numerical simulation of the Navier‐Stokes equations in finite‐volume formulation. The turbulent viscous stresses are accounted for by means of eddy viscosity model. For the discretization of the space around the sings 0‐0 grid topologies have been used. The analysis includes the study of the spiraling vortices in the cross‐flow fields comprising velocity and pressure distributions yield further essential results, including total forces and moments of the wings. The computation method is applicable for subsonic, transonic and supersonic onflow Mach numbers. The numerical results are well validated with experimental data.
