      Kjølaas, Jørn; Belt, Roel; Wolden, Marita; Schümann, Heiner; Richon, Vanessa (Peer reviewed; Journal article, 2021)
      A set of two- and three-phase experiments were conducted in a 50 m long 400 vertical pipe using nitrogen, Exxsol D60 and water at 45 bara pressure. The results show that the liquid content and pressure drop are highly ...
