Popis:	The vorticity cone nement technique, which represents a very effective, unie ed way of treating complex, highReynolds-number separated e ows with thin convecting vortices, as well as thin attached boundary layers, over complex solid bodies. Conventional Eulerian computational methods are discussed and then contrasted with vorticity cone nement, which is also Eulerian. The basic assumptions in vorticity cone nement, are reviewed, and then the method itself is briee y outlined. Following the description, representative results are presented: First, two-dimensional results for convecting vortices and Cauchy ‐Riemann e ow over a cylinder are presented. These describe, respectively, the salient features of the method for convecting vortices and for e ow over solid surfaces, embedded in a uniform Cartesian grid. Then, three-dimensional results for e ow over complex cone gurations, including a complete rotorcraft, are presented.
