• Cohesive collisions of particles in liquid media studied by CFD-DEM, video tracking, and Positron Emission Particle Tracking 

      Saparbayeva, Nazerke; Chang, Yu-Fen; Kosinski, Pawel Jan; Hoffmann, Alex Christian; Balakin, Boris; Struchalin, Pavel (Journal article; Peer reviewed, 2023)
      This paper investigates the cohesive collision of ice in an oil phase at temperatures ranging from −15.7 °C to −0.3 °C. The new information on the coefficient of restitution (COR) was obtained using three different velocity ...
    • A note on the multiphase balance equations 

      Hoffmann, Alex Christian (Journal article; Peer reviewed, 2020)
      The formulation and use of the momentum equations for multiphase systems are not always consistent in the literature. The objective of this note is to clarify an issue, which long has hounded the literature on the multiphase ...
    • Theoretical analysis of erosion in elbows due to flows with nano- and micro-size particles 

      Kosinska, Anna Dorota; Balakin, Boris; Kosinski, Pawel Jan (Journal article; Peer reviewed, 2020-02-05)
      The present paper focuses on the issue of erosion due to fluid flow laden with nano- and microparticles. We investigated the case of a pipe elbow using theoretical analysis and numerical simulations. For the case when the ...
