Problems of and prospects for the investigation of the thermal conditions of blades of high-temperature gas turbines (a review based on presentations to the Third Russian National Conference on Heat Transfer)

Experimental and theoretical analytical studies are reviewed which are devoted to the problems of cooling blades of high-temperature gas turbines and were reported at the Third Russian National Conference on Heat Transfer. The thermal conditions of the external surface of blades with internal convection cooling were investigated in experimental test stands and in the operating GTE-150 facility. The mathematical simulation was reported in a large number of presentations, many of which involved the use of the latest commercially available computer codes of the type of STAR-CD, FLUENT, and others. Special attention is given to studies into the heat transfer and hydrodynamics under conditions of convection-film cooling of blades and of most advanced penetration porous cooling of hot stages of gas-turbine plants.
