METHOD FOR SOLVING THE PROBLEM OF FREE SPREADING OF A TURBULENT POTENTIAL FLOW BEHIND A PRESSURE-FREE PIPE

The paper substantiates the design scheme and General formulation of the method for solving the problem of coupling various flows necessary in the practice of hydraulic engineering construction of GTS. In the scheme given in the article, when solving the problem of free spreading of a turbulent two-dimensional water flow with a uniform flow, a simple wave borders, and not a General flow, such as a radial flow. The analysis of the three characteristic zones of the flow. It is proved that a turbulent flow under free spreading transforms into a radial one, and the elements of the radial expansion of the flow are determined. The equations for determining the geometric shape and flow parameters for all three sections of the flow with its free spreading are obtained. The research results in this paper are obtained for the first time and complete the research started in the works of other authors.
