Abstract
PURPOSE: To cool the entire surface of gas-turbine blade uniformly, by increasing the coefficient of heat transfer of coolant and improving blade cooling effect of the coolant by charging filler material in coolant passage, and thereby attaining uniform distribution of coolant temperature and heat transmitting efficiency in the coolant passage.
CONSTITUTION: Coolant introduced from coolant supply port 4 flows into coolant passage 2', and passing through the small spaces formed between particles of filler material, is discharged to the outside from coolant outlet ports 5, 6. When filler material 7 is charged into passage 2', coolant flow is disturbed considerably and its velocity becomes high, so that heat transmitting efficiency of the coolant becomes high and resultantly its cooling effect is enhanced. Further, since coolant is mixed or agitated efficiently, coolant passage 2' can be cooled uniformly throughout the entire surface thereof, so that the entire surface of blade 1' can be cooled uniformly.
