    • 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; Tidsskriftartikkel; Peer reviewed, 2023-05-18)
      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 measurement methods: high-speed experimental video recording, Positron Emission Particle Tracking (PEPT), and numerical simulations. A new type of PEPT tracer was developed for ...

    • Novel bio-compatible tracers for Positron Emission Particle Tracking 

      Chang, Yu-Fen; Balakin, Boris (Conference object; Konferansebidrag, 2020-09)
      To study the flow of objects (tracers) in opaque flow processes, the PEPT (positron emission particle tracking) technique is utilized. The PEPT technique is based on the same principle of PET (positron emission tomography) which detects the characteristic back-to-back gamma pairs caused by positron-electron annihilation. The annihilation takes place within a few millimeters around the tracers labeled ...
