수평 원형전열관의 핀효과에 의한 응축 및 비등 열전달촉진에 관한 연구 (2)-튜브외부 응축-
A Study on the Improement of Condensation and Boiling Heat Transfer on Horizontal Tube by Fin Effect(ll)-Shellside Condensation-
초록
Heat transfer performance improvement by fin and grooves is studied for condensation of R-11 on integral-fin tubes. Eight tubes with trapezoidal shaped integral-fins having fin densities from 748 to 1654 fpm and 10, 30 grooves are tested. A plain tube having the same diameter as the finned tubes is also tested for comparison. R-11 condenses at saturation state of
