Instabilities of Dynamic Thermo- and Solutocapillary Liquid Layers
The variation of the surface tension with temperature and concentration constitutes a driving mechanism known as Marangoni convection. We study a coupled thermo- and solutocapillary surface-tension-driven shear flow in an unbounded plane layer. The basic flow can be calculated analytically. The stability of the flow is investigated by a linear analysis. Results are presented for some special contributions and for Pr = 1 and Sc = 100.
