Two-phase flow frictional pressure drop of FC-14 in horizontal tubes

ABSTRACT
Experimental measurements on the two-phase flow frictional pressure drop of tetrafluoromethane (FC-14) were carried out with a pressure of 0.4 MPa and the mass flow rates ranging from 240 to 785 kg/m2s. The influences of the mass flow rate and quality on the friction pressure drop were analyzed. The experimental results have been compared with three widely used correlations, of which proposed by Zhang and Webb (2001) gave a best agreement with the deviation in 16%.
