A METHOD FOR MANUFACTURING A HEAT TRANSFER DESIGN FOR PROGRESSIVE HEAT TRANSFER CAPABILITY COOLING CHANNELS

摘要

A method for manufacturing a heat transfer design for progressive htc cooling channel arrangements for a region of a gas turbine engine is provided. The 5 method includes generating a non-transitory computer-readable three-dimensional (3D) model of the cooling channel, which includes cooling sections adapted for use in component with various component regions, with some sections having cooling flux mitigation adaptations to overcome the effects of increased temperature in the component regions to maintain efficient cooling effectiveness throughout the cooling channel sections. Adaptations may include regions of cross sectional area that increases heat transfer effectiveness, as well as regions characterized by an increase in lateral flow compared to longitudinal flow.
