Analytical Solution of the Task of Boundary Determining of Flow Spreading

A mathematical model of a two-dimensional high-speed flow in terms justification and taking into account several physical assumptions is formulated. The problem solved analytically the plane velocity hodograph to determine all parameters flow. coupling uniform with general form "simple wave" made it possible achieve reduction error model. adequacy pre-sented method shown.
 existing models are described that insufficiently acceptable adequate geometry boundary, but large mismatch local depths velocities. new as whole characterized by convergence both (flow spreading boundaries) kinematics (depth velocity) increased 18% directions.
 section should be well combined real flow, ac-count forces resistance boundaries use proposed belong expansion 3-7 b required reference literature, have been clarified earlier works. model, shown article, takes (experimental) consistent previously performed theoretical studies. An important conclusion article values Froude criterion can any range from 1 infinity, at same time "$X_D^I$" increase in-creasing number.
