    • Dissipation rate estimation in a rectangular shaped test section with periodic structure at the walls 

      La Forgia, Nicolas; Herø, Eirik Helno; Solsvik, Jannike; Jakobsen, Hugo Atle (Journal article; Peer reviewed, 2018)
      An experimental study of turbulent flow concerning the characterization of turbulence by two-point correlation and estimations of the turbulent dissipation rate is presented. The fluid used is deionized water and the test ...

    • Experimental Investigation of Single Bubbles Rising in Stagnant Liquid: Statistical Analysis and Image Processing 

      Kure, Ida Kristine; Solsvik, Jannike; Jakobsen, Hugo Atle; La Forgia, Nicolas (Peer reviewed; Journal article, 2021)
      Despite the large effort devoted to the study of single bubbles rising in a stagnant liquid, the complex phenomena involved have resulted in a large scatter in the terminal velocity. Providing new experimental data where ...

    • Experimental study of multiphase flow in an upward-inclined pipe 

      Kallager, Magnus; Vassmyr, Marit (Master thesis, 2017)
      This work has been dedicated to gain knowledge about two-phase flow in an inclined pipe through experimental investigation and adaption of theoretical framework from relevant literature. Two-phase flow experiments with ...

    • Experiments on Single Droplet Breakage in Turbulent Flow 

      Dahl, Ingeborg (Master thesis, 2019)
      Hensikten bak denne masteroppgaven er å studere oppbrytningen av enkeltdråper i en turbulent strømning. Oppgave tar for seg flere steg i studien av oppbryting av dråper, inkludert utførelse av eksperimenter på lab, bruk ...

    • Single Drop Breakage in Turbulent Flow: Statistical Data Analysis 

      Herø, Eirik Helno; La Forgia, Nicolas; Solsvik, Jannike; Jakobsen, Hugo Atle (Peer reviewed; Journal article, 2020)
      To improve breakage models in the population balance framework, single octanol droplet experiments have been performed in a channel flow and recorded by high-speed camera. The study investigates impact of mother drop size ...

    • Small scale severe slugging experiments with several risers 

      Solstad, Ingrid Sofie (Master thesis, 2015)
      Severe slugging is a multiphase flow phenomenon that can occur in flowline-riser systems when conditions allow it. Its periodical fluctuations in pressure and mass flow can cause operational problems in downstream processing ...
