In the present work

a rotating platform was established

whereby the experiment for investigating flow and heat transfer characteristics of the steam-water two-phase mixture flowing in a pipe positioned in radius direction of the platform was conducted by means of electric heating.The test section was a plexiglass circular tube with inner diameter of 20 mm and length of 400 mm.Different gravities were obtained by changing rotational speed

and the effect of gravity on the heat transfer characteristic of steam-water flow was investigated.The results show that the bigger the gravity

the higher the pressure and flow resistance

and the lower the flow rate

the lower the void and the heat transfer capability

as well as the bigger the heat transfer coefficient in outside pipe.
