Stability of thermocapillary flow in a flat layer with allowance for the Soret effect
E. A. Ryabitskii Institute of Computer Simulation, Siberian Division, Russian Academy of Sciences, Krasnoyarsk, 660036, Russia
Abstract:
The stability of thermocapillary two-component liquid flow is studied taking into account thermal diffusion. An explicit expression is obtained to construct neutral Marangoni numbers under the assumption of monotonicity of perturbations. The thermocapillary and hydrodynamic instability mechanisms are considered. It is shown that plane perturbations are the greatest hazard to the stability of return flow.
Keywords:
stability, thermocapillary flow, thermal diffusion, Marangoni number, neutral curve.
