ABSTRACT

Effects of surfactant concentration on gas-liquid slug flow in circular microchannels were investigated experimentally. Pressure drop and void fraction were measured using a high-speed video camera and an image processing method. Deionized water with surfactant was used as the liquid phase, and N2 gas was used as the gas phase. Triton X-100 was used as the surfactant. The diameters of the microchannels used in the experiment were 320 and 500 μm. The measured data were compared with experimental data in a clean system obtained in our previous study. The following conclusions were obtained: (1) the surfactant deformed bubble rear shapes without affecting the front shapes; (2) the bubble radius reduction region decreased with an increase in the void fraction and increased with the surfactant concentration; (3) the pressure drop in the contaminated systems was larger than that in the clean system; and (4) the relationship between the void fraction and gas volumetric flow ratio was not affected by the surfactant in the present experimental condition, therefore, the void fraction could be predicted using the drift flux model with an applicable distribution parameter model in a clean system.
