반동도에 따른 증기터빈의 설계 및 성능 해석을 컴퓨터 시뮬레이션으로 수행하였다. 깃 각도와 출구면적, 노즐면적과 같은 설계변수들과 터빈동력, 선도효율, 축방향 추력과 같은 성능변수들을 반동도에 따라 나타내었다. 추가적인 설계 및 성능변수에 대한 정보를 제공하기 위하여, 깃 각도와 터빈동력, 선도효율, 축방향 추력과 같은 주된 설계 및 성능변수들을 유동계수(주속도에 대한 축방향속도)의 함수로 제시하였다. 터빈동력, 선도효율을 최대로 하는 반동도 및 유동계수가 존재함이 밝혀졌으며, 반동도가 증가함에 따라 동익의 깃 형상은 대칭형으로부터 많이 벗어남을 보여주었다.
Design and performance analysis of a steam turbine for variations of degree of reaction were performed by computer simulation. Design parameters such as blade angles, exit areas, and heights of the nozzle and moving blade were represented as functions of the degree of reaction. The main performance factors such as turbine power, diagram efficiency, and axial thrust were also expressed in terms of the degree of reaction. For further information about the design and performance, the blade angles and main performance factors were investigated as functions of the flow coefficient. The turbine power and diagram efficiency reached a maximum value for a given degree of reaction and flow coefficient, and the symmetric shape of the moving blade showed distortion as the degree of reaction was increased.
