On Application of Vortex Frames in Method of Vortex Blobs

The modification of a method of vortex blobs is considered for designing a three-dimension flow around bodies of an ideal liquid and calculating non-steady loads. As vortex blobs, spherical vortexes are used. To satisfy a boundary condition on the body surface, vortex frames are applied. An algorithm is described; results of the test design of the flow around a sphere are given.
