    • A new Norwegian bioeconomy based on cultivation and processing of seaweeds: Opportunities and R&D needs 

      Skjermo, Jorunn; Aasen, Inga Marie; Arff, Johanne; Broch, Ole Jacob; Carvajal, Ana Karina; Christie, Hartvig C; Forbord, Silje; Olsen, Yngvar; Reitan, Kjell Inge; Rustad, Turid; Sandquist, Judit; Solbakken, Roar; Steinhovden, Kristine; Wittgens, Bernd; Wolff, Robert; Handå, Aleksander (Research report, 2014)
    • A Wall-Function Approach for Direct Precipitation/Crystallization Fouling in CFD Modelling 

      Johnsen, Sverre Gullikstad; Johansen, Stein Tore; Wittgens, Bernd (Conference object; Lecture; Peer reviewed, 2015)
      The main objective of this paper is to present a generic modelling framework, for the diffusive mass transport through the turbulent, reactive boundary layer of multi-component fluid mixtures that ...
    • Efficacy of a novel sequential enzymatic hydrolysis of lignocellulosic biomass and inhibition characteristics of monosugars 

      Baksi, Sibashish; Ball, Akash K.; Sarkar, Ujjaini; Banerjee, Debopam; Wentzel, Alexander; Preisig, Heinz A.; Kuniyal, Jagdish Chandra; Birgen, Cansu; Saha, Sudeshna; Wittgens, Bernd; Markussen, Sidsel (Peer reviewed; Journal article, 2019)
      Efficient production of sugar monomers from lignocellulose is often hampered by serious bottle-necks in biomass hydrolysis. The present study reveals that ultra-sonication assisted pretreatment following autoclaving, termed ...
    • Implementation, Demonstration and Validation of a User-Defined Wall Function for Direct Precipitation Fouling in Ansys Fluent 

      Johnsen, Sverre Gullikstad; Pääkkönen, Tiina; Johansen, Stein Tore; Keiski, Riitta; Wittgens, Bernd (Conference object; Lecture, 2017)
      In a previous paper (Johnsen et al., 2015) and presentation (Johnsen et al., 2016), we developed and demonstrated a generic modelling framework for the modelling of direct precipitation fouling from multi-component fluid ...
    • Implementation, Demonstration and Validation of a User-Defined Wall Function for Direct Precipitation Fouling in Ansys Fluent 

      Johnsen, Sverre Gullikstad; Pääkkönen, Tiina; Johansen, Stein Tore; Keiski, Riitta; Wittgens, Bernd (Chapter, 2017)
      In a previous paper (Johnsen et al., 2015) and presentation (Johnsen et al., 2016), we developed and demonstrated a generic modelling framework for the modelling of direct precipitation fouling from multi-component fluid ...
    • Studies on delignification and inhibitory enzyme kinetics of alkaline peroxide pre-treated pine and deodar saw dust 

      Baksi, Sibashish; Sarkar, Ujjaini; Saha, Sudeshna; Ball, Akash K.; Kuniyal, Jagdish Chandra; Wentzel, Alexander; Birgen, Cansu; Preisig, Heinz A.; Wittgens, Bernd; Markussen, Sidsel (Journal article; Peer reviewed, 2019)
      Delignification of lignocellulosic biomass by alkaline peroxide pre-treatment is a preliminary important step for an overall biomass fractionation process. In the present work, saw dusts are pre-treated by aqueous alkaline ...
