Void Fraction Two-Phase Flow of Air - Sodium Chloride Solution and Glucose in Horizontal Mini-Pipe

Abstract:

Experimental research was conducted on a horizontal mini-pipe to obtain primary data on the effect of different glucose concentrations on the void fraction. The experiment was performed on a test section using a 1.6 mm diameter mini glass pipe in a horizontal position. The gas phase consisted of dry air, and the liquid phase was a 0.9% sodium chloride solution with glucose concentrations of 5% and 10%. The superficial gas velocity (J_G) ranged from 0.083 m/s to 74.604 m/s, while the superficial liquid velocity (J_L) ranged from 0.041 m/s to 4.145 m/s. Void fraction data was obtained using a high-speed camera, and the results were processed through image analysis. The detected flow patterns were plug, slug-annular, annular, bubble, and churn. The stratified flow pattern was not observed in this study. An increase in JG generally results in an increase in the void fraction (ε).
