Abstract

The invention discloses a modeling method for aerodynamic-dehumidification-cooling test of a turbine blade, comprising three parts: a modeling method for aerodynamic test of a turbine blade, a modeling method for a dehumidification test of a turbine blade and a modeling method for a cooling test of a turbine blade . Among them, the turbine blade aerodynamic test modeling method includes three processes: aerodynamic test structure similarity modeling, aerodynamic test flow similarity modeling and aerodynamic test result modeling transformation; turbine blade dehumidification test modeling method includes dehumidification test structure similarity modeling There are three processes: performance modeling, dehumidification test flow similarity modeling, and dehumidification test result modeling transformation; turbine blade cooling test modeling methods include cooling test structure similarity modeling, cooling test flow heat transfer similarity modeling and cooling There are three processes for the model conversion of test results. Adopting the modeling method of the invention can greatly save the test cost and the test cycle, and further shorten the product development cycle of the turbine blade.

Description

technical field [0001] The invention belongs to the technical field of turbines, in particular to a modeling method for aerodynamic-dehumidification-cooling tests of turbine blades. Background technique [0002] Turbine is a kind of high-speed rotating machinery, which is widely used in thermal power generation, nuclear power, aerospace, ship propulsion and industrial drive and other fields. It is a high-end industry that countries focus on investing and competing for development. During the working process of the turbine, the working fluid flows through the cascade channel, and drives the rotor blades to rotate, and transmits the rotational torque to the rotating shaft through the wheel disc, thereby driving the generator to generate electricity or output power externally. [0003] As one of the core components of the turbine system, the blade not only has to withstand the high-temperature and high-pressure environment of the working medium, but also is affected by the air...
