Numerical simulation of leading-edge vortex flow

An analysis is presented of results of a computational method to simulate the steady compressible vortical type of flow around a 65-deg sharp-edged cropped delta wing. The discussion emphasizes some more fundamental aspects of the numerical simulation such as the separation of the flow, the structure of the leading-edge vortex core and the flow...

An approximate method for computing inviscid vortex wake roll-up. Part I: Theory and application

In this report an approximate method is described for computing, through the unsteady analogy, the shape of steady vortex wakes downstream of aircraft configurations in steady flight. In the analogy the steady fully three-dimensional problem is reduced to a two-dimensional timedependent problem, corresponding to the evolution of a two...
