Feedback control of oscillatory thermocapillary convection in a half-zone liquid bridge
Active feedback control was applied to suppress oscillations in thermocapillary convection in a half-zone liquid bridge. The experiment is on a unit-aspect-ratio liquid bridge where the most unstable azimuthal mode has wavenumber 2 when control is absent. Active control was realized by locally modifying the surface temperature using the local temperature measured at different locations fed back...
متن کاملMultistability of oscillatory thermocapillary convection in a liquid bridge.
A parametric investigation of the onset of chaos in a liquid bridge was numerically carried out for a medium Prandtl number liquid, Pr = 4, and unit aspect ratio under zero-gravity conditions. Spatiotemporal patterns of thermocapillary flow were successively studied beginning from the onset of instability up to the appearance of the nonperiodic flow and further on. Well-tested numerical code is...
متن کاملBifurcation analysis of the thermocapillary convection in cylindrical liquid bridges
We consider the instability of the steady, axisymmetric thermocapillary convection in cylindrical liquid bridges. Finite-difference method is applied to compute the steady axisymmetric basic solutions, and to examine their linear instability to three-dimensional modal perturbations. The numerical results show that for liquid bridges of O(1) aspect ratio Γ (=length/radius) the first instability ...
متن کاملActive control of oscillatory thermocapillary convection.
Active control of oscillatory thermocapillary flow was applied in an open cylindrical container filled with silicone oil. Thermocapillary convection was driven by imposing a radial temperature gradient on a flat free surface. The control was realized by locally heating the surface at a single position using the local temperature signal at a different position fed back through a simple algorithm...
متن کاملLinear Oscillatory Cellular Thermocapillary Convection in Liquid Layers
A linear stability analysis is performed on a thermal, stratified liquid layer with a deformable thermocapillary surface. The objective is to investigate the possibility and conditions for existence of oscillatory cellular convection in the linear thermocapillary system. In general, the principle of the exchange of stabilities for the onset of cellular convection in liquid layers with deformabl...
