    "abstract": "The classical Helmholtz problem is applied for modelling the axisymmetric\ninviscid cusp-ended separated flow around a sphere. Two coordinate systems are\nemployed: polar for initial calculations and parabolic the latter being more\nsuitable for investigation of infinitely-long stagnation zones. Scaled\ncoordinates are introduced and difference schemes for the free-stream equation\nand the Bernoulli integral are devised. The separation point is not initially\nprescribed and is defined iteratively. A separated flow with vanishing drag\ncoefficient is obtained.",
