초록

대기압 상태인 물의 내부에 설치된 튜브의 경사각이 풀비등 열전달계수에 미치는 영향을 확인하기 위하여 새로운 실험식을 개발하였다. 실험과 기존에 발표된 결과들에 대한 조사를 통하여 431개의 실험값을 결정하였으며, 회귀분석 기법으로 비선형 최소자승법을 사용하였다. 열유속($0{\sim}120kW/m^2$), 경사각($0^{\circ}{\sim}90^{\circ}$), 튜브 길이를 직경으로 나눈 값(18~42.52)을 주요 매개변수로 선정하였다. 새롭게 개발된 상관식은 약간의 예외를 제외하면 실험값을 ${\pm}18%$ 범위 내에서 잘 예측한다.
