A method for controlling the cooling air flow in a turbine blade and turbine blade with a flow control means comprises

摘要

A coolant flow control structure (42) is provided to channel cooling media flow to the fillet region (60) defined at the transition between the wall of a nozzle vane (16) and a wall (12) of a nozzle segment, for cooling the fillet region. In an exemplary embodiment, the flow control structure defines a gap (65,67) with the fillet region to achieve the required heat transfer coefficients in this region to meet part life requirements.
