Simulations of vortical flow fields over conical delta wings are carried out, using Euler and 'thin-layer' Navier-Stokes equations to examine the reliability of the Euler separations. The computations over elliptic cones indicate that crossflow shock wave location is well predicted by the Navier-Stokes computations, but not well predicted by the Euler computations. The examination of the time evolution of the leading-edge separation reveals that the origin of the leading-edge separation in the Euler solution is the shock-induced separation. However, this is not a physical shock-induced separation and the entropy production at the leading-edge due to numerical dissipation is an important factor. The computations over circular-tip delta wings reveal that the large leading-edge separation for the Euler solutions are actually the shock-induced separation near the leading-edge.
