좁은 수평 환형 Crevice에서의 증발열전달촉진에 관한 연구
Study on enhancement of evaporating heat transfer in narrow horizontal annular crevices
- 발행 : 1996.04.01
초록
This study is intend to improve flow pattern within evaporator, which is low quality and low mass flux, by installing narrow horizontal annular crevice so that enhance heat transfer coefficient. The motive, which made to study heat transfer enhancement by using narrow annular crevice, came from capillary phenomena and pumping force of generating vapor on refrigerant boiling. Tests were run about 5 models of turbulence promoter with CFC-12, in the range of evaporating temperature (15.deg. C), mass flux (50 to 100 kg/m
