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 breaking mechanisms. The effect of increase in the plate thickness on the limit steepness of the regular flexural-gravity wave and its dissipative properties is considered. The critical plate thickness corresponding to the maximum wave steepness is found. For the plate thickness below this value the vibrations of the hydroelastic system are determined by the gravity waves, while for the greater thickness the vibration mechanism relates to the flexural waves. The non-exponential nature of damping of the flexural-gravity waves is revealed. [ABSTRACT FROM AUTHOR]

The results of the experiments on the influence of a positive-buoyancy-particle layer on the process of breaking and regularization of the standing gravity Faraday wave on free water surface in a rectangular vessel are discussed. The effect of increase in the particle layer thickness on the limit steepness of the regular wave and its dissipative properties is considered. It is shown that the use of highly concentrated polystyrene particle suspension as the upper layer modifies significantly the barotropic wave mode dynamics and ensures regularization of the waves with total suppression of their breaking mechanisms.

Important physical models involving boundary layer occur in almost all internal and external aerodynamic formations. For many of these, the flow outside the boundary layer region may be determined into a large principal component and a small crosswise velocity. In this article, three-dimensional boundary-layer flow over a curved surface is treated for nanofluid under such a simplification. Based on strong thermal conductivity we have considered two same kinds but different shaped nanoparticle namely: Single Wall Carbon Nanotubes (SWCNT) and Multiple Wall Carbon Nanotubes (MWCNT) which are incorporated within the base fluid water. Mathematical model is constructed under the constraint of defined geometry and then transformed into the system of ordinary differential equations. These equations are solved numerically with the help of Runge Kutta (R-K) method with shooting technique. Influences of each physical parameter on velocity and temperature distribution are described through graphs. To analyze the drag and heat transfer at the surface we have plotted the skin friction coefficient and local Nusselt number. Flow behavior along the stream wise and cross direction is visualized through stream lines. It is found that viscous dissipation has same increasing effects along both x- and z-directions for temperature profile however, SWCNTs have comparatively higher skin friction and heat transfer rate at the surface as compare to the MWNTs.
