Line-Vortex Models of Separated Flow Past a Circular Cone at Incidence.
Abstract
The simple line-vortex model of laterally-symmetric separated flow past a circular cone at incidence, originally proposed by Bryson, is studied in detail, both numerically and analytically through asymptotic expansions. Two branches of solutions are found, an 'upper' branch which includes Bryson's original results, and a lower branch, on which the solutions are found to be physically unrealistic. The physically realistic branch is shown to yield multiple solutions for separation lines to windward of a critical position. A proposed modification to the condition imposed on the flow at the separation line is shown to have little effect on the behavior of the model. (Author)
