Summary

In order to make a detailed understanding of the cryogenic turbo-expander off-design performance at cool-down procedure, an extensive experimental and numerical program have been carried out on a mixed and inward flow radial turbine. According to the design and cooling process condition, just like pressure at stator inlet or brake power of the turbo-expander, a series of CFD simulations were carried out in order to guide design and off-design iterations towards achieving a matched flow capacity for each situation. The analyses also include the study of the effect of different gas models on the CFD calculations. Through the results analysis it was concluded that the direct use of the Hepak database for the real gas properties in the CFD solver improve the prediction of the thermodynamic properties and so the performance of the turbo-expander. With experimental comparison, the cryogenic turbo-expander off-design performance at cooling process can be better known.
