On the vortex flow over delta and double-delta wings

An experimental and theoretical investigation is described of the flow above and downstream of a 76° delta wing and two double-delta wings (sweep 76°/60° and 76°/40°, respectively, kink at 50 % chord). The flow pattern is visualized employing a laser-light-sheet technique. For the case of the delta wing experimental results are compared with...

A higher order panel method applied to Vortex sheet roll-up

The paper describes a computational method for two-dimensional vortex sheet motion in incompressible flow. The procedure utilizes a second-order panel method, an adaptive panel scheme and a concept for treating highly rolled-up portions of the vortex sheet. Results are presented for the roll-up of the wake behind an elliptically loaded wing, a...

A Higher-order panel method for the computation of the flow about slender delta wings with leading-edge vortex separation

For the limiting cases of conical flow about delta wings and time dependent 2-D development of the wake behind the trailing edge of wings a new second-order panel method is described. It is demonstrated that the panel method is stable for the mixed design/analysis boundary conditions characterizing both problems. The method for following 2-D...
