다양한 작동 조건에서 임펄스 터어빈 시스템의 성능 예측에 관한 연구

Abstract

This paper deals with the design and analysis of a 250kW-class impulse turbine for wave energy conversion. Numerical analysis was performed using FLUENT. The size and the performance of turbine for providing a demanding power could be estimated using a series of performance chart built through the present study. Temporal and spatial variations of flow field were also considered to compare with those of uniform inflow. It was concluded that a rather simple steady flow analysis still provided the practically useful way for the design and performance prediction of turbine using performance charts.
