AB - The multi-channel cylinder dryer uses the small channels with high heat transfer efficiency to improve the drying efficiency. In practical working conditions, the multi-channel cylinder dryer runs under the rotating state, which would greatly affect the pressure drop of inside two-phase steam. However, the condensation friction pressure drop of two-phase flow in rotating channels has not been well explored. Herein, the condensation pressure drop of two-phase steam in rotating rectangular channels are elaborately studied based on a homemade rotating experiment system. The results show that the friction pressure drop of two-phase flow decreases with the increase of rotation Reynolds number, while increases with the increase of mass flux. Finally, a new correlation of friction pressure drop for two-phase flow condensation in rotating channels is proposed and evaluated by the experimental data.
