| Abstract: | The mechanism of heat transfer enhancement of forced convective condensation with noncondensable gas on spiral grooved tube with baffle rods has been analyzed. The experimental results show that the baffle-rod induced stronger turbulence in two phase flow and enhanced the heat and mass transfer. In the experiment range, the overall heat transfer coefficients has been magnitude as a factor of 0.9-2.5 comparing with a plain tube at the same conditions. |
