Вычислительные технологии для метода дискретных вихрей

Abstract

Computing technologies for approximating continuous boundaries by an ordered system of discrete vortices in the problems of modeling flat transient flows using discrete vortices method is considered. The method and algorithm developed allow computing continuous characteristics determined by multivalued functions in their domains up to the boundaries, which are the natural separation lines of the continuous characteristics. The method and algorithm for transforming discrete singularities proposed in the paper can be applied for the boundaries of arbitrary geometry, e.g. branching contours or closed loops. The relations obtained allow computing kinematic and dynamic characteristics for separated flows taking into account the new boundary segments arising at the separation points.
