Abstract—The results of the experiments on the influence of a polyethylene-foam floating thin plate on the process of breaking and regularization of the standing gravity Faraday wave on free water surface in a rectangular vessel are discussed. It is shown that the presence of the plate leads to regularization of the waves with suppression of their ...

Abstract—The problem of the development of thermomechanical waves in the system consisting of two horizontal layers with rheology of a linearly elastic medium for the upper layer (lithosphere) and a viscous fluid for the lower layer (asthenosphere) is considered with regard to phase transition on their common boundary. The exact solution to the pro...

AbstractElectrothermal convection demonstrates the huge potential for the active enhancement of heat transfer, but an in-depth understanding of many related processes is still superficial. In this paper, electrothermal convection subjected to unipolar injection within rectangular cavities is investigated. A series of simulations under different Ray...

AbstractThe investigation of shock wave boundary layer interaction (SWBLI) and the prediction of the associated flow field and surface property variation are essential elements in designing scramjet engine. Therefore, the present study on SWBLI is carried out numerically on a two-dimensional scramjet intake model. The effect of various free-stream ...

A two-dimensional pulsating flow of a viscous fluid in a plane channel whose wall has rectangular microcavities partially or completely filled with a compressible gas is investigated. This problem formulation can clarify the friction reduction mechanism in a laminar sublayer of a turbulent viscous boundary layer flow over a textured stripped superh...

AbstractThe hydrodynamic action on long thin beams executing bending resonance vibrations in a fluid near a plane rigid surface (surface) is investigated. The model of quasi-two-dimensional interaction between the fluid and the beam is used, according to which the hydrodynamic action on any beam cross-section can regarded as a result of plane flow ...

Abstract—The problem of the far field of internal gravity waves generated by a perturbation source of radial symmetry aroused at an initial instant of time is solved. The constant model distribution of the buoyancy frequency is considered and, using the Fourier–Hankel transform, an analytical solution to the problem is obtained in the form of the s...

Abstract—The problem of absorption by a resonator of a gravity wave that propagates on the surface of an incompressible fluid is solved. The resonator is small as compared with the wavelength. For the free fluid surface the resonance, i.e., maximally possible, absorption cross-sections of resonators of various types are found. It is shown that the ...

Abstract—In this study, the interaction between a spherical solid particle descending in a fine-bubble plume and the fine-bubbles around the particle is investigated experimentally. The fine-bubbles, which are formed by water electrolysis and have an average diameter of 0.037 mm, rise via buoyancy to form bubble plumes. The average bubble velocity ...
