ABSTRAKT

The results of development and numerical investigation of thermal protection of the surfaces immersed in a disperse working fluid flow in relation to turbomachine blades are presented. The possibility of increasing the accuracy of prediction of the thermal state of blades by obtaining reliable data with the aid of the developed mathematical model and the unique complex of modeling programs is shown. The possibilities and conditions of increasing the efficiency of turbine blades cooling by using damping cavities are investigated.
