Vibrational convection in the Hele–Shaw cell. Theory and experiment
I. A. Babushkin, V. A. Demin Perm' State University, Perm', 614990, Russia
Abstract:
The influence of high-frequency horizontal vibrations on convection in the Hele–Shaw cell located in a uniform gravity field is considered experimentally and theoretically. Nonlinear regimes of vibrational convection in the supercritical region are examined. It is shown that horizontal vibrations (directed toward the wide sides of the cell) decrease the threshold of quasi-equilibrium stability. Regions of existence of one- and two-vortex steady flows are found, and unsteady regular and random regimes of thermal vibrational convection are considered. New random regimes in the Hele-Shaw cell are found, which result from nonlinear interaction of the “lower” modes responsible for the formation of regular supercritical convective regimes.
Keywords:
thermal vibrational convection, Hele–Shaw cell, regular and random flows.
