A preliminary experimental study was carried out to investigate the flow and heat transfer characteristics of condensed steam flowing in a horizontal pipe under dynamic load generated with a rotational platform. By changing parameters such as rotation speed, inlet temperature and flow rate of cooling water, inlet pressure of steam, some flow and thermodynamic date of steam condensation under both static and rotating states were obtained, and were analyzed. The results show that the dynamic load dramatically influences the condensation process of the steam in a horizontal pipe.
