Hydrothermal-wave instabilities in thermocapillary convection are known to produce undesirable effects when they occur during the float-zone crystal-growth process, and perhaps in other situations. Suppression of the hydrothermal-wave instability produced in the model system of Part 1 (Riley & Neitzel 1998) is demonstrated through the sensing of free-surface temperature perturbations and the periodic addition of heat at the free surface along lines parallel to the crests of the… Expand
Instability of thermocapillary–buoyancy convection in shallow layers. Part 1. Characterization of steady and oscillatory instabilities
Combined thermocapillary–buoyancy convection in a thin rectangular geometry is investigated experimentally, with an emphasis on the generation of hydrothermal-wave instabilities. For sufficientlyExpand
Effects of curvature on hydrothermal waves instability of radial thermocapillary flows
Abstract The stability of a thermocapillary flow in an extended cylindrical geometry is analyzed. This flow occurs in a thin liquid layer with a disk shape when a radial temperature gradient isExpand
Suppression of Oscillatory Thermocapillary Convection in Thin Liquid Layers
Experiments have been performed to examine the feasibility of suppressing oscillatory thermocapillary convection in thin liqiidlayers of silicone oil. The existence of these oscillations is due toExpand
Numerical characterization of hydrothermal waves in a laterally heated shallow layer
Instabilities of a buoyancy-thermocapillary flow in a three-dimensional differentially heated layer have been examined by means of direct numerical simulations, in order to have a more detailedExpand
Bifurcation of thermocapillary convection in a shallow annular pool of silicon melt
In order to understand the nature of surface patterns on silicon melts in industrial Czochralski furnaces, we conducted a series of unsteady three-dimensional numerical simulations of thermocapillaryExpand
Elastic instability in the thermocapillary convection at low Reynolds numbers
Abstract It is well known that the plane channel flows of UCM and Oldroyd-B fluids are linearly stable at low Reynolds numbers. However, an elastic instability is detected by modal analysis in theExpand
Convective Instability in Annular Pools
The convective instabilities in semiconduc- tor or oxide melts, significantly affect the quality of large crystals grown from the melts by the Czochralski method. This paper reviews our recentExpand
Oscillation Transition Routes of Buoyant-Thermocapillary Convection in Annular Liquid Layers
There are various oscillation transition routes of buoyant-thermocapillary convection in an annular liquid layer. Three types of transition routes including quasi-periodic bifurcation,Expand
Instabilities in two-liquid layers subject to a horizontal temperature gradient
We study theoretically the stability of two superposed fluid layers heated laterally. The fluids are supposed to be immiscible, the interface undeformable and of infinite horizontal extension.Expand
Linear and nonlinear stability of hydrothermal waves in planar liquid layers driven by thermocapillarity
A shallow planar layer of liquid bounded from above by gas is set into motion via the thermocapillary effect resulting from a thermal gradient applied along its interface. Depending on the physicalExpand
