Abstract
A number of papers[1–9] have appeared in recent years reporting numerical solutions of the Euler equations for flows past sharp edge delta wings with leading edge vortices. A schematic diagram of the problem under consideration is shown in Figure 1. Solutions have been compared with experiment [1,8], with incompressible panel method calculations [6], with other Euler equation solutions [8,5], and with Navier-Stokes calculations [9]. Although one cannot conclude that these comparisons show complete agreement, it is reasonable to say that they establish that finite volume calculations of the Euler equations appear to give reasonable predictions of the primary vortex generated by this configuration. A point of some concern in these papers [1,3,4] relates to the mechanism by which the Euler equations cause the flow to separate from the body and form a strong vortex which has associated with it a significant total pressure loss.
