A numerical study of flow field and particle deposition in nasal channels with deviant geometry
Thune, Eveline Løvaas; Kosinski, Pawel Jan; Balakin, Boris; Alyaev, Sergey (Peer reviewed; Journal article, 2021)Deviant geometry of nasal channels results in significant changes to nasal aerodynamics that alter flow resistance, sensation, and the ability to filter aerosols. The invasive, operative modification of nasal geometry might ... -
Performance of a tubular direct absorption solar collector with a carbon-based nanofluid
Struchalin, Pavel; Yunin, Vladimir; Kutsenko, Kirill V.; Nikolaev, Oleg; Vologzhannikova, Alisa; Shevelyova, Marina; Gorbacheva, Olga; Balakin, Boris (Peer reviewed; Journal article, 2021)Direct absorption solar collectors (DASC) with nanofluid represent a new direction in solar thermal technology that is simpler yet more efficient than conventional equipment. In this work, we report details of performance ... -
Photothermal convection of a magnetic nanofluid in a direct absorption solar collector
Balakin, Boris; Stava, Mattias; Kosinska, Anna Dorota (Peer reviewed; Journal article, 2022)Nanofluid-based direct absorption of solar heat results in thermal efficiencies superior to conventional solar thermal technology. In addition, convection of nanofluid can be sustained pump-free in the collector. In this ... -
Photothermal conversion of biodegradable fluids and carbon black nanofluids
Kosinska, Anna Dorota; Balakin, Boris; Kosinski, Pawel Jan (Peer reviewed; Journal article, 2022)The paper is devoted to the topic of direct absorption solar collectors (DASCs). Various kinds of fluids can be used as heat transfer fluid in DASCs, and the main focus of our paper is on comparing nanofluids (water with ... -
Solar-driven desalination using nanoparticles
Kuzmenkov, Dmitrii M.; Struchalin, Pavel G.; Olkhovskii, Andrey V.; Yunin, Vladimir S.; Kutsenko, Kirill V.; Balakin, Boris (Peer reviewed; Journal article, 2021)Due to the high light absorption and the possibility of localizing boiling to the interior of the receiver, nanoparticles are promising for solar-driven desalination. The paper presents an experimental study of the ... -
Theoretical analysis of erosion in elbows due to flows with nano- and micro-size particles
Kosinska, Anna Dorota; Balakin, Boris; Kosinski, Pawel Jan (Peer reviewed; Journal article, 2020)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 ... -
Use of biodegradable colloids and carbon black nanofluids for solar energy applications
Kosinska, Anna Dorota; Balakin, Boris; Kosinski, Pawel Jan (Peer reviewed; Journal article, 2021)The conversion of solar energy to heat can be performed in direct absorption solar collectors, where the radiation from the sun is absorbed by a fluid. There are various types of fluids that can be used, and recently, ... -
Viscosity of ice-in-oil slurries
Naukanova, Madina; Lavalle, Gianluca; Herri, Jean-Michel; Cameiro, Ana; Struchalin, Pavel; Balakin, Boris (Peer reviewed; Journal article, 2023)Ice slurries are phase change materials extensively used in refrigeration technology. This work describes an experimental study and empirical modeling that was carried out to characterize the rheological behavior of ... -
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 ...
