The novel technology was developed of heat transfer, gasdynamics, and film cooling efficiency prediction of high-performance gas turbine blades providing high accuracy of calculations.This technology takes into consideration stationary conditions and rotation of of cooled surface, blowing ratio, external flow speed, surface geometric shape (flat, concave, or convex), surface indentations configuration (spherical or rectangular), multi-row of coolant supply.

Using the experimental and theoretical approach both heat transfer and gas-dynamics of two complex vortex and swirling flows have been studied in details. New regularities regarding the local and average heat transfer have been established in the cylindrical channel with initial tangentially-inclined flow swirl at the stationary conditions, as well as in the radial rotating channel. The new similarity correlations have been obtained for the different boundary conditions arranged at the channel exit.
