限定条件下における気液二相流モデルの進展

Gas-liquid two-phase flows exist in a wide range of applications and enabling technologies. If, however, “understanding” we mean that the phenomenon in two-phase flow system can be predicted in terms of governing parameter, it should be concluded that two-phase flow is poorly understood item, and many questions are still open. A thorough theoretical approach with such microscopic experimental results as three-dimensional and high spatiotemporal measurements is needed to assess the performance of gas-liquid two-phase flow. My study of gas-liquid two-phase flows at microgravity conditions and in small diameter pipe is outlined in this report, especially for which regarding to interfacial area transport and drift flux. Research on two-phase at micro- or reduced-gravity conditions and in small pipe is expected to be conducted more widely in the future, shedding light on two-phase flow phenomena in piping system.
