Abstract: Pipe-net calculation of air-cooled turbine blade is the important segment of air-cooled
turbine blade heat transferring design, aiming at the requirement on heat transfer design for air-cooled
turbine blades, the method of heat transfer analysis data extraction for air-cooled turbine blade model
is proposed, which include the algorithms of computing units division, automatic judgment of air path,
network diagram generation and data automatic extraction for heat transfer analysis, etc. Combined
with the characteristics of air-cooled turbine blade structure, a data extraction system for heat
transferring analyzing was developed based on UG Open API. The functions of extracting heat
transfer analysis data of air-cooled turbine blade for subsequent analysis and calculation has been
achieved, and the automatic degree of heat transferring calculation has been heighten, and the
modeling result validated the feasibility of our method.
