Abstract

A performance analysis program of a disk type fluidic valve was developed to predict a chamber pressure and a response time. A parametric study of this device was performed by using scattering plot method. A sensitivity of Mach number at a nozzle outlet showed the highest value about a outlet diameter of nozzle. An inlet flow rate is the most important parameter to design the fluidic valve because it has high sensitivity value both a outlet velocity and a response time.

유동 제어 시스템에 적용을 위한 디스크형 유체 소자 밸브의 성능해석 알고리즘을 수립하고 설계 변수들에 대한 민감도 분석을 진행하였다. 유입 유량 발생에 따른 챔버의 압력 변화와 디스크 거동 변화를 예측 하였고 설계 변수들의 민감도 분석을 위해 Scattering plot 기법을 활용하였다. 민감도 분석결과 유동 마하수에 가장 큰 민감도는 갖는 변수는 노즐 출구이며 밸브 응답 시간과 노즐 출구 모두에서 큰 민감도를 갖는 변수는 유입 유량임을 확인하였다.
