유로형상변화에 따른 터빈성능 변화의 수치적 해석
Numerical Investigation of the Effect of Turbine flow Passage Variation on the Turbine Performance
- 발행 : 2005.12.01
초록
A turbopump turbine consists of rotational part including a rotor and stationary part including nozzles and exit guide vanes, of which shape and relative position affect turbine performance owing to supersonic flows with prevailing unsteadiness. In this study, numerical 3-D flow calculations of the turbine with the different number of exit guide vanes and different relative position of each component are conducted and the effect of flow passage variations on turbine performance is analyzed.
