| Abstract:Condensation heat transfer in multi-channel cylinder dryer was numerically simulated with Fluent software using VOF two-phase flow model. The rotational speed was chosen as variable. The condensate volume, condensation heat transfer coefficient and pressure drop were obtained. The simulation result showed that the condensate volume, condensation heat transfer coefficient and pressure drop were increased with the increasing of rotational speed, but the increase rate tended to decrease. |
