Effect of geometric parameters of liquid-gas separator units on phase separation performance

Abstract

Five liquid-gas separator units were designed and constructed based on a new concept of a validated high-performance condenser. Each separator unit consiss of two united T-junctions and an apertured baffle. The separator units have different header diameters or different baffles with different diameters of the liquid-gas separation hole. The phase separation characteristics of the units were investigated at inlet air superficial velocities from 1.0 m/s to 33.0m/s and water superficial velocities from 0.0015 m/s to 0.50 m/s. The experimental results showed that the liquid height, liquid flow rate through the separation hole, and liquid separation efficiency increased with increased header diameter and decreased diameter of the separation hole. The geometric structures of the separator units affected the phase separation characteristics by influencing the liquid height in the header and the liquid flow rate through the separation hole.
