| 英文摘要 | in this paper, preliminary experimental results are presented on pressure drop characteristics of single and two-phase flows through two t-type rectangular microchannel mixers with hydraulic diameters of 528 and 333 mum, respectively. it is shown that both n-2 and water single-phase laminar flows in microchannels, with consideration of experimental uncertainties, are consistent with classic theory, if additional effects, such as entrance effects that will interfere with the interpretation of experimental results, are eliminated by carefully designing the experiments. the obtained pressure drop data of n-2-water two-phase flow in micromixers are analyzed and compared with existing flow pattern-independent models. it is found that the lockhart-martinelli method generally underpredicts the frictional pressure drop. thereafter, a modified correlation of c value in the chisholm's equation based on linear regression of experimental data is proposed to provide a better prediction of the two-phase frictional pressure drop. also among the homogeneous flow models investigated, the viscosity correlation of mcadams indicates the best performance in correlating the frictional pressure drop data (mean deviations within +/-20% for two micromixers both). finally it is suggested that systematic studies are still required to accurately predict two-phase frictional performance in microchannels.
