Scaling law for capillary-driven flows
Fedorchenko, Alexander I. ; Stachiv, Ivo
Theoretical investigation of the capillary-driven flows has been carried out. Based on the virial theorem it has been proven that a family of the capillary-driven flows is described by power laws with an universal set of exponents: 3/2, – 1/3, – 1/2 which interrelate the characteristic spatial (L), temporal (T) and velocity (U) scales.
On phenomenon of the rotating inertia-gravity wave formation at in- and outflow of the liquid from cylindrical container
Fedorchenko, Alexander I. ; Stachiv, Ivo
Experimental observations of the spontaneous formation of the rotating inertia-gravity wave inside cylindrical container have been carried out. The experimental setup combines both inflow and outflow. The inflow is realized as the overflow of liquid over the container’s edge, while the outflow is performed through an outlet at the bottom of the container’s center. Experiments revealed three different regimes of establishment flow inside the container: 1) flow without formation of the inertia-gravity wave, 2) flow with surface perturbations which are initially localized nearby the container’s wall, and 3) the formation of the rotating inertia-gravity wave.
