“…It means that a non-equilibrium medium with the density profile has supplies of available potential energy. The latent energy is converted into the kinetic energy of the liquid flow in a thin layer of DiF near an inclined impermeable surface, on The main stratification parameter, the buoyancy period T b , was measured with an optical instrument [58] or an electrical conductivity sensor [59] in a short internal wave field around a density marker-a vertical wake past a rising gas bubble or a sinking crystal (salt or sugar). The bubble floated (the crystal sank) vertically if the Reynolds number, determined by its diameter D and velocity U, satisfied the condition Re = UD/ν < 201.…”

This study presents the detailed experimental results of fine structures and dynamics in a stratified flow past a sphere, which is towed with constant velocity in a transparent basin. We developed experimental procedures based on the complete solutions of the truncated fundamental fluid equations. These complete solutions describe the waves and fine accompanying ligaments, as well as the vortices and other flow structures. To visualize the flow, a variety of classical schlieren and electrolytic precipitation procedures were used. Ligaments appear in the schlieren images of the flow as fine interfaces and fibers. They strengthen the influence of the relatively weak density gradient in a continuously stratified fluid (CSF). The symmetry in the wake is discrete at small Froude numbers with the domination of buoyancy effects. At increased velocity and high Froude numbers, when the inertial and non-linear effects turn out to be significant, an axial symmetry becomes continuous.

“…The light source is narrow slit placed vertically in conventional schlieren method with Foucault's knife or Maksutov's "slit-thread" instrument as well as horizontally with a regular grating providing natural "rainbow" colour schlieren image [14]. Prior to each test, the buoyancy period 2 b TN  is determined with accuracy better than 5% by measurement of salinity oscillations using conductivity probe near a density marker [15]. The marker is formed by a vertical wake past a free-falling salt/sugar crystal or a small vertically arising gas bubble, and is also used for measurement of horizontal velocity component and buoyancy period profiles [16].…”

The paper presents numerical and experimental study of 2D stratified flow around a strip based on the system of incompressible viscous fluid mechanics equations taking into account stratification and diffusion effects and neglecting heat transfer. The computations show the flow structure is essentially unsteady and multiscale with space-time scales, manifestation degree and attenuation rate of the flow structural elements being significantly affected by variations in values of the basic parameters of the moving body, i.e. size, shape, angle of attack, and movement velocity. For all the problem parameters considered, the laboratory and calculated instantaneous flow patterns indicate a complex unsteady nature of mutual interaction of all the flow components, including waves, vortices, and ligaments, and show a good qualitative agreement of the results of numerical and laboratory modeling.
