SOLUTION OF THE PROBLEM OF FREE FLOW OF ROUGH TWO-DIMENSIONAL WATER FLOW WHEN FLOWING OUT OF A PRESSURE-FREE PIPE

The authors improved the solution of the problem of free spreading of two-dimensional in terms of turbulent potential uniform flows obtained by I.A. Sherenkov. To obtain an analytical solution, the concept of a general flow is used. The conjugation of the solution in the physical plane and in the plane of the velocity hodograph (virtual plane) is used. This made it possible to determine the coordinates of the points of the extreme current line and determine the current parameters leading to an unambiguous analytical solution of the flow geometry.
