In the conventional multiphase flow, immiscible multiphase flow, having a liquid-liquid interface, two immiscible liquids are merged in the flow path to form a liquid-liquid interface. The two-phase separation mixed solution has the property of phase-separating from one phase to two phases by changing the temperature/pressure, and phase-separates into the upper and the lower phases in the batch-type vessel. By changing the phase while sending this mixed solution to a micro-space region, a liquid-liquid interface is formed and a multiphase flow is obtained. This flow is called phase-separation multiphase flow. The circular flow in the micro-space, which is one of the phase-separation multiphase flows, is interesting and has been applied to chromatography, extraction, mixing, and reaction space. Here, the author comprehensively introduces our previous research reports on phase-separation multiphase flow from an academic and technical perspective.
