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 ... -
Eco-friendly and low-cost nanofluid for direct absorption solar collectors
Balakin, Boris; Struchalin, Pavel (Peer reviewed; Journal article, 2023)Nanofluids are promising receivers for solar collectors with volumetric absorption. These solar collectors are 1.2…1.4 times more efficient than conventional technology. However, most of the considered nanofluids are ... -

Struchalin, Pavel; Øye, Vegar Hovdenakk; Kosinski, Pawel Jan; Hoffmann, Alex Christian; Balakin, Boris (Peer reviewed; Journal article, 2022) -
Hybrid Nanofluid in a Direct Absorption Solar Collector: Magnetite vs. Carbon Nanotubes Compete for Thermal Performance
Struchalin, Pavel; Kuzmenkov, Dmitrii M.; Yunin, Vladimir S.; Wang, Xinzhi; He, Yurong; Balakin, Boris (Peer reviewed; Journal article, 2022)The paper presents the experimental measurements of thermal efficiency of a tubular direct absorption solar collector (DASC) with a hybrid nanofluid based on magnetite (Fe3O4) and multi-walled carbon nanotubes (MWCNT). The ... -
Influence of Particle Size Distribution on the Optical Properties of Fine-Dispersed Suspensions
Kuzmenkov, Dmitrii; Struchalin, Pavel; Litvintsova, Yulia; Delov, Maksim; Skrytnyy, Vladimir; Kutsenko, Kirill (Peer reviewed; Journal article, 2022)Nanofluids have great potential for solar energy harvesting due to their suitable optical and thermophysical properties. One of the promising applications of nanofluids is utilization in solar collectors with the direct ... -
