摘要

Experiments of steam-water two-phase flow heat transfer in two vertical helical coils were carried out in the high-pressure steam-water test loop of Xi'an Jiaotong University. The coil is used in the steam generator (SG) of a high-temperature gas-cooled test reactor HTR-10. Two kinds of tube with inner diameters of 10mm and 12mm respectively were used to form the coils. The helix diameter was very small, its value was 115mm, and the pitch of the coils was 22.5mm. The experimetanl conditions were: pressure p=4-14MPa, mass velocity G=400-2000kg/(m~2 centre dot s), inner wall heat flux q=150-750kW/m~2. Theoretical analysis was made and semi-empirical correlations were given to predict the two-phase convection heat transfer and post-CHF heat transfer in the helical coils.
