The paper presents the results of an experimental study of the properties of single-and multiphase flows in a “pore doublet model” (PDM) using microfluidic and optical microscopy techniques. Polymer based microfluidic devices containing pore doublet were fabricated using soft lithography methods. The average cross-section of the microchannels was in the order of 100 μm, and the length reached several millimeters. A bubble generator in the form of a T-junction microchannel was fabricated to study the multiphase flows. High speed imaging and tracer visualization methods were used to study the flow patterns. The properties of multiphase flows were studied during liquid-gas displacement and bubbly liquid flow through pore doublet. The flow patterns were visualized using polymer micro particles suspended in flowing liquids.
