• closedAccess   Flow regime development analysis in adiabatic upward two-phase flow in a vertical annulus 

      Juliá Bolívar, José Enrique; Ozar, Basar; Jeong, J.J.; Hibiki, Takashi; Ishii, M. Elsevier (2011)
      In this work radial and axial flow regime development in adiabatic upward air–water two-phase flow in a vertical annulus has been investigated. Local flow regimes have been identified using conductivity probes and neural ...
    • closedAccess   Flow structure of gas-liquid two-phase flow in an annulus 

      Ozar, Basar; Jeong, J.J.; Dixit, A.; Juliá Bolívar, José Enrique; Hibiki, Takashi; Ishii, M. Elsevier (2008)
      The flow structure of gas-liquid two-phase flow in vertical annulus channel has been investigated. The inner and outer diameters of the annular channel were 19.1 and 38.1 mm, respectively. The total height of the test ...
    • closedAccess   Interfacial area transport of vertical upward air-water two-phase flow in an annulus channel 

      Jeong, J.J.; Ozar, Basar; Dixit, A.; Juliá Bolívar, José Enrique; Hibiki, Takashi; Ishii, M. Elsevier (2008)
      An experimental study on the interfacial area transport (IAT) of vertical, upward, air-water two-phase flows in an annulus channel has been conducted. The inner and outer diameters of the annular channel were 19.1 mm and ...
