2Although NMR technique has been using in many areas of chemistry, its merit on quantitative analysis seems not to acknowledge greatly because of the many inferior intrinsic aspects, particularly its sensitivity. Recently, new NMR techniques, high-field NMR, and demands for cutting edge techniques of analysis, however, seem to change the role of NMR spectroscopy in this field. This review shows the application of NMR development in quantitative analysis and will discuss the basic idea, limitation
판토그라프 팬헤드의 공력소음 발생의 주요 인자와 영향을 미치는 변수를 분석하였다. 팬헤드 주변의유체 유동과 결과적인 소음 방사를 분석하기 위해, 수치해석적인 방법 중 하나인 격자볼츠만 방법으로 팬헤드단순모델을 사용했다. 풍동실험을 통해 측정된 결과로 시뮬레이션 결과를 검증했다. 와흘림이 주요한 공력소음발생원인이며 Strouhal수, 유체의 속도 및 판토그라프의 형상에 영향을 받았다. 이 논문에 사용된 직사각형 형상을 통해 양력의 발생을 증가시키면서 방사 소음을 줄이는 팬헤드의 설계가 가능함을 제시하였다. 또한 통로나유선 형상을 이용해 와흘림을 최소로 줄이면, 방사 소음을 크게 저감하는 형상의 설계가 가능함을 구축된 해석모델을 이용하여 검증하였다.
