소형 액체 추진시스템의 배관 유동특성 해석

Piping was designed for researching cluster effect on small liquid propulsion system. Analysing by the Flowmaster S/W, expected pressure peak, caused by closing flow control valve, was 2.5 higher than nominal operating pressure. To reduce the pressure peak, Accumalator was installed on the pipe line and it showed reduced pressure peak as much as 1.6 timed higher than operating pressure. To verify this effect, test bench was manufactured and water flow test was performed. And the result showed validity of analysis.
