    Spatio-Temporal Variations of River Water Quality for Material Processing Purposes

    Tatyana Lyubimova, Anatoly Lepikhin, Yanina Parshakova, Andrey Bogomolov, Alibek Issakhov
    FDMP-Fluid Dynamics & Materials Processing, DOI:10.32604/fdmp.2025.061649

    Abstract The article presents the results of in-kind measurements and numerical modeling of the formation of water characteristics in the Kama River, which is used for technical water supply in the production of potash fertilizers. In the warm season, risks arise that threaten the sustainability of the water supply. It was found that in the summer, when the studied section of the Kama River is backed up by the Kama Hydroelectric Power Station, there is a significant decrease in flow rates, which leads to vertical stratification of water properties. This, in turn, significantly limits the possibilities… More >

    Effect of Libration on Fluid Flow and Granular Medium Dynamics in a Rotating Cylindrical Annulus

    Denis Polezhaev, Alexey Vjatkin, Victor Kozlov
    FDMP-Fluid Dynamics & Materials Processing, DOI:10.32604/fdmp.2025.062000

    Abstract The dynamics of fluid and non-buoyant particles in a librating horizontal annulus is studied experimentally. In the absence of librations, the granular material forms a cylindrical layer near the outer boundary of the annulus and undergoes rigid-body rotation with the fluid and the annulus. It is demonstrated that the librational liquefaction of the granular material results in pattern formation. This self-organization process stems from the excitation of inertial modes induced by the oscillatory motion of liquefied granular material under the influence of the gravitational force. The inertial wave induces vortical fluid flow which entrains particles More >

    Inertial Modes in a Rotating Horizontal Annulus with Boundaries of Different Temperatures and Their Effect on the Averaged Convection

    Alexey Vjatkin, Svyatoslav Petukhov, Victor Kozlov
    FDMP-Fluid Dynamics & Materials Processing, DOI:10.32604/fdmp.2025.062535
    (This article belongs to the Special Issue: Non-Equilibrium Processes in Continuous Media)
    Abstract Time-averaged thermal convection in a rotating horizontal annulus with a higher temperature at its inner boundary is studied. The centrifugal force plays a stabilizing role, while thermal convection is determined by the “thermovibrational mechanism”. Convective flow is excited due to oscillations of a non-isothermal rotating fluid. Thermal vibrational convection manifests in the form of two-dimensional vortices elongated along the axis of rotation, which develop in a threshold manner with an increase in the amplitude of fluid oscillations. The objective of the present study is to clarify the nature of another phenomenon, i.e., three-dimensional convective vortices… More >

    Effect of Surface Tension on the Dynamics of an Oscillating Interface in a Vertical Slotted Channel

    Veronika Dyakova, Olga Vlasova, Victor Kozlov
    FDMP-Fluid Dynamics & Materials Processing, Vol.21, No.3, pp. 493-508, 2025, DOI:10.32604/fdmp.2025.060577
    (This article belongs to the Special Issue: Non-Equilibrium Processes in Continuous Media)
    Abstract An experimental investigation of the dynamics of the interface between two low-viscosity fluids with high density contrast oscillating in a fixed vertical slotted channel has been conducted. It has been found that as the amplitude of the liquid column oscillations increases, parametric oscillations of the interface are excited in the form of a standing wave located in the channel plane. In particular, depending on the interfacial tension, the standing waves have a frequency equal to that of liquid piston oscillations (harmonic response), or half of the frequency of oscillations of the liquid column in the… More >

    Diffusive Transfer between a Droplet and an Immiscible Oscillating Liquid in a Radial Hele-Shaw Cell

    Ivan Karpunin, Denis Polezhaev
    FDMP-Fluid Dynamics & Materials Processing, Vol.21, No.3, pp. 543-553, 2025, DOI:10.32604/fdmp.2025.061163
    (This article belongs to the Special Issue: Non-Equilibrium Processes in Continuous Media)
    Abstract An experimental study of the diffusive mass transfer between a droplet and an oscillating immiscible liquid in a horizontal axisymmetric Hele-Shaw cell is carried out. The liquid oscillates radially in the cell. The transverse size of the droplet exceeds the cell thickness. The viscosities of the droplet and the surrounding liquid are comparable. Relevant effort is provided to design and test an experimental setup and validate a protocol for determining the mass transfer rate of a solute in a two-liquid system. In particular, fluorescent dye Rhodamine B is considered as the solute. A critical comparison… More >

    Inertial-Wave Regime of Averaged Thermal Convection in a Rotating Vertical Flat Layer

    Kirill Rysin, Alexey Vjatkin, Victor Kozlov
    FDMP-Fluid Dynamics & Materials Processing, Vol.21, No.3, pp. 605-621, 2025, DOI:10.32604/fdmp.2025.061722

    Abstract Thermal vibrational convection (TVC) refers to the time-averaged convection of a non-isothermal fluid subjected to oscillating force fields. It serves as an effective mechanism for heat transfer control, particularly under microgravity conditions. A key challenge in this field is understanding the effect of rotation on TVC, as fluid oscillations in rotating systems exhibit unique and specific characteristics. In this study, we examine TVC in a vertical flat layer with boundaries at different temperatures, rotating around a horizontal axis. The distinctive feature of this study is that the fluid oscillations within the cavity are not induced… More >
