Experimental study on steam-water two-phase flow frictional pressure drops in helical coils

摘要

Experiments of steam-water two-phase flow frictional pressure drop in a vertical helical coil were carried out in the high-pressure water test loop of Xi'an Jiaotong University. The coil is made of stainless steel tube with an inner diameter of 16 mm, the helix diameter Measured from tube axis to tube axis is 1.3m, and helix angle of the coil is 3.65°.
