평판의 Perforation에ㅐ 의한 유동저항 및 전열특성

Abstract

구멍이 있는 평판 전열면에 구멍의 크기 및 배열 방식이 마찰손실의 증가에 대하여 전열특성의 증가에 미치는 상대적 영향을 실험적으로 규명하였다.

실험결과는 구멍의 크기가 적고, 구멍간의 간격을 감소 시켰을 때 열전달 성능은 압력손실의 증가에 비하여 크게 향상되었다.

The experimental study is carried out to investigate the relative increase of heat transfer performance in contrast to friction loss along the perforation diameter of plates or their arrangements.

The Data of results indicate that when perforation diameter is small and its pitch is short the perforation of plates increase heat transfer performance without a large friction loss penalty.
