Test section details:

The test section is made of acrylic resin to observe the flow pattern in the air/water experiment.

Components details:

The ranges of dimensions of experimental tubes were as follows : diameter D : 0.026-0.076 m, length of horizontal tube H : 0.01-0.4 m, length of inclined riser : 0.038-0.6 m and inclination angle of inclined riser : 40° or 45°. The separator tank has a 0.21 mx0.21 m square cross section and 0.38 m height. A water injection pipe of 0.03 m I. D. is attached at the bottom of the separator tank. The top of the separator tank is open to the atmosphere with a pipe of 0.1 m J.D. The upper space of the measuring tank has a 0.21 m x 0.21 m x 0.21 m cubic shape and an air injection pipe of 0.015 m I. D. is attached at the top of this space. Air is injected from a compressor through a regulation valve and a rotameter. The lower space of the measuring tank has a 0.31 m X 0.31 m rectangular cross section and 1. 0 m height. To measure water levels, both in the separator tank and the lower space of the measuring tank, the level meters are attached at the side wall of each tank.
