Annotations languages:

There are the results of hydrodynamic similarity currents analysis and research data of generalization technique on the edge surfaces as curvilinear channels and nozzles of gas turbines with commensurable sizes of blades height and its pitch. As the result there is an equation of local heat exchange similarity in curvilinear channels and nozzles of the gas turbines and it calculates the influence of current curvature lines, spatiality of current in the interface, a longitudinal gradient of pressure, effects of running off stream in the field of the bent and leakage in the field of convex surfaces of profiles of shovels are received.
Keywords: secondary current, edge nozzle surfaces of the gas turbine, the analysis of stream similarity, research data of generalization technique, an equation of local heat exchange similarity on the edge surfaces
