    • Determination of Breakage Parameters in Turbulent Fluid-Fluid Breakage 

      Herø, Eirik Helno; Forgia, Nicolas La; Solsvik, Jannike; Jakobsen, Hugo Atle (Journal article; Peer reviewed, 2019)
      Numerous sets of single‐particle breakage experiments are required in order to provide a sufficient database for improving the modeling of fluid particle breakage mechanisms. This work focuses on the interpretation of the ...

    • 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 Investigations of Single Oil Droplet Breakage in a Turbulent Water Flow 

      Herø, Eirik Helno (Doctoral theses at NTNU;2021:340, Doctoral thesis, 2021)
      Multiphase flow and the transient behavior of the dispersed phase is important to numerous industrial applications. Predictive modeling of the dispersed phase would be beneficial in designing, for example, phase separation ...

    • Microfluidic method for determining drop-drop coalescence and contact times in flow 

      Dudek, Marcin; Fernandes, Diana; Herø, Eirik Helno; Øye, Gisle (Peer reviewed; Journal article, 2020)
      Coalescence kinetics is an important parameter when describing the stability of dispersions. A number of methods to measure coalescence time are available, however they often take long time and do not allow working with ...

    • Programming turbulence models in FORTRAN 

      Herø, Eirik Helno (Master thesis, 2015)
      The two-equation turbulence models Wilcox k-omega and Menter k-omega SST are programmed in FORTRAN and tested on the cases channel flow and backward-facing step. A short time step and a good initial field is required to ...

    • 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 ...
