ALGORITHM FOR THE CONJUGATION OF TWO-DIMENSIONAL IN THE PLAN OF UNIFORM AND RADIAL FLOWS

The algorithm of the theoretical method proposed by the authors using the speed hodograph plane and simple waves for solving the problem of coupling a two-dimensional flow in terms of flow is considered. This technique allows you to determine the boundaries of the free flow of a turbulent flow and its parameters in the flow area. it is revealed that using both planes physical OXYZ and hodograph G (,) it is possible to solve the problem uniquely analytically. All verification calculations were performed in the MathCad package. The calculation results showed a satisfactory convergence of model and experimental parameters in the free flow model, which does not exceed 10 % by error before the flow expansion within  = 7;  = B/b.

SIMPLE WAVES IN THE THEORY OF TWO-DIMENSIONAL WATER FLOWS AND THE SCHEME OF THEIR USE FOR FREE FLOW SPREADING
