Description

벽을 통해 유출하는 확산기
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 외부벽의 돌출부내의 유출스롯트에 축방향의 입구를 가지는 확산기에 흐름의 제1 혹은 원하는 바의 형식을 나타내는 도면.
제2도는 제1도에서 나타낸 것과 같은 확산기에 있어서 흐름의 제2 혹은 원하지 않는 형식을 나타내는 도면.
제3도는 본 발명과 일치하는 확산기의 단면도.

Claims (6)

  1. 확산기가 축 ＡＡ′에 대하여 대칭이며 상기의 축에 유체입구 상기 유체입구로부터 유체출구로 인도되는 돌출된 외부벽 그리고 상술한 외부벽의 돌출한 부분에서 상술한 축 ＡＡ′주위에 대칭적으로 배열된 원형 유출 스롯트를 포함하며 그러므로써 상술한 외부벽을 상류부분과 하류부분으로 나누고 여기에서 상기한 둘출된 외부벽은 작동 중에 상술한 벽의 표면을 따라서 유체의 흐름방향이 상술한 상류부분위와 상술한 벽의 하류부분 위에서 상술한 입구로부터 상술한 출구로 향하도록 하기 위한 윤곽을 가지고 있으며 여기에서 유체 흐름의 상술한 방향에서 상술한 벽을 따르며 상술한 표면에서 측정된 압력구배는 상술한 스롯트로부터 상류에서 부이며 그것으로부터 하류에서는 정인 것을 특징으로 하는 벽을 통하여 유출하는 확산기.
  2. 제1항에서 상술한 스롯트가 축 ＡＡ′를 따라서 흐름의 방향으로부터 측정된 100°및 120°에 놓여있는 입구각도를 가지며 청구범위 1에 따르는 확산기.
  3. 제1 또는 제2항에서 상술한 스롯트가 실질적으로 다음과 같은 입구폭 bopt를 가지며 청구범위 1 혹은 2에 따르는 확산기 :
    여기서
    X는 유출비 즉 스롯트를 통한 유출량/확산기에의 전체유입량 :
    S0는 확산기의 유입단면 :

    V1은 스롯트로의 입구에서 회부벽의 상류부분위의 유체속도 :
    그리고
    R1은 스롯트로의 입구에서 외부벽의 상류부분의 만곡부의 반경.
  4. 앞의 어느 항에서 외부벽의 하류부분이 다음과 같거나 혹은 약간 더 큰 거리에 의하여 외부벽의 상류 부분의 후단에 비하여 상쇄되는 선단부분을 외부벽의 하류부분이 가지며 진술한 어떤 청구범위에 따르는 확산기 :
    여기서
    X는 유츌비 즉 스롯트를 통한 유출량/확산기에로의 전체유입량 :
    S0는 확산기의 유입단면 :
    V0는 확산기의 유입단면에서의 평균 유체속도 :
    r는 스롯트와 축사이의 반경방향의 거리 :
    V1은 스롯트에의 입구에서 외부벽의 상류부분위의 유체속도 :
    그리고
    R1은 스롯트에의 입구에서 외부벽의 상류부분의 만곡부의 반경 :
    상술한 상쇄는 축에 수직이고 외부벽의 하류부분의 후단에 점선방향인 상류평면과 축에 수직이고 외부벽의 하류부분의 선단끝의 원형단면의 중앙을 통과하는 하류평면 사이의 거리로써 정의되는 것.
  5. 앞의 어느 항에서 확산기로부터 출구각도 약 90°이며 전술한 어떤 청구범위에 따르는 확산기.
  6. 첨부 도면의 제3,4,5,6,7,8,9도를 참조하여 본질적으로 여기에 기술된 바와 같은 확산기.
