Abstract

The thermocapillary flows and their stability in an infinite liquid column surrounded by a co–axial gas layer with a given flow rate are investigated. The gas layer is surrounded by a rigid cylindrical surface, which can move in vertical direction. A constant axial temperature gradient is maintained in the layers. The exact solution describing the stationary flow in the given two–phase system is derived. Possible flow regimes are investigated and linear stability analysis of these regimes is performed. The cases of non–deformable and deformable interface are studied.
