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 (Peer reviewed; Journal article, 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 ... -
Visualization of Unsteady Flow in a Multistage Helico-Axial Pump
Gundersen, Ted Ørjan Seim; Moënne-Loccoz, Victor; Dupoiron, Marine; Torbergsen, Erik Andre; Balakin, Boris; Arntzen, Bjørn Johan; hoffmann, alex christian (Journal article, 2023)Helico-axial pumps are designed to pump mixtures of gas and liquid. Secondary flows and rotor-stator interactions are known to add complexity to the flow field in unshrouded axial-flow turbomachinery. Here we use a high-speed ...
