| Abstract: | In the paper, the analyzing model of the flow boiling and two-phase-flow pressure drop of Rodbaffle reboiler with thread tube were presented. The experimental results and testing curves were given. It showed that Pressure drop in reboiler is so low and but the highest enhanced effects is 2 7~3 9 times as bare tube bundle |
