| 英文摘要 | This paper developed a new type of three dimensional inner microfin tube. The experimental results of the flow patterns for the horizontal condensation inside these tubes are reported in the paper. The flow patterns for the horizontal condensation inside the new made tubes are divided into annular flow, stratified flow and intermittent flow within the test conditions. The experiments of the local heat transfer coefficients for the different flow patterns have been systematically carried out. The experiments of the local heat transfer coefficients changing with the vapor dryness fraction have also been carried out. As compared with the heat transfer coefficients of the two dimensional inner microfin tubes, those of the three dimensional inner microfin tubes increase 47^-127Vo for the annular flow region, 38~183Vo for the stratified flow and 15~75% for the intermittent flow, respectively. The enhancement factor of the local heat transfer coefficients is from l.8~6.9 for the vapor dryness fraction from 0.05 t0 1. |
