| 英文摘要 | this paper presents an experimental investigation on influence of liquid physical properties and channel diameter on gas-liquid flow patterns in horizontal circular microchannels with inner diameters of 302, 496 and 916 mu m. several liquids with different physical properties, i.e. water, ethanol, three sodium carboxymethyl cellulose (cmc) solutions (0.0464%, 0.1262%, 0.2446% cmc) and two sodium dodecyl sulfate (sds) solutions (0.0608%, 0.2610% sds) are chosen as working fluid and nitrogen as working gas. by using a high-speed photography system, flow patterns such as bubbly flow, slug and unstable slug flow, churn flow, slug-annular and annular flow are observed and identified on the flow regime maps. the results show that the liquid physical properties (viscosity and surface tension) and channel diameter affect the flow pattern transitions remarkably. comparison with existing models in literature implies that these transitions cannot be well predicted. as a result, an effort is put into the proposition of a new empirical model taking the effects of channel size and liquid physical properties into account.
