The present work reports a conjugate heat transfer analysis of a turbine blade exposed to
high-temperature compressible gas flow and the convection cooling inside the blade. A
nickel-based superalloy material CMSX-4 with better mechanical and anticorrosive
properties has been introduced for blade materials, and grooved channels are proposed for
heat transfer enhancement in internal convection. Each channel contains nine mini-grooves
having groove-depth to channel-diameter ratio in the range of 0.08–1.12. Three prominent …
