구심터빈 성능예측을 위한 상용프로그램의 적용성 평가

Abstract

Radial-type turbines have been used in small power generation systems as well as aircraft engines since the mid-20th century. It is also a core part of the turbocharger, so much research has been conducted. In addition, commercial software for performance prediction and design have been released. Recently, many research results have been published for the performance prediction and design of radial-type turbines for Organic Rankine Cycle using a working fluid as a refrigerant instead of air using a commercial software. Therefore, in this study, a performance prediction technique was developed based on the loss models with the experimental results, and then it was expanded to estimate the acceptability of a commercial software with the working fluid of refrigerant. In conclusion, it is important to recognize the range of error in performance prediction according to the application of commercial software.
