The paper presents the results of development and validation of a network mathematical model and a numerical algorithm for calculating two-phase flows of immiscible liquids in highly branched microchannel systems. The hydrodynamic model is based on the pore-network approach, which provides a significantly higher computational speed compared to the methods of computational fluid dynamics. Validation of the developed mathematical model and numerical algorithm was carried out on experimental data obtained on the problems of single-phase and two-phase flows in microfluidic chips. Satisfactory qualitative and quantitative agreement between the results of experiments and calculations was obtained.
