Influence of Heat Flux Modulation on Thermocapillary Instability in a Binary Mixture with the Soret Effect

摘要: We study the influence of modulation a heat flux on Marangoni convection in layer binary mixture with Soret effect. A linear stability analysis is performed numerically by means Floquet theory for both longwave and shortwave perturbations. For mode we also apply an empirical criterion stability, which implies that noise finite magnitude present system. It shown destabilizes layer. However, this destabilization rather strong only negative values number, when either or oscillatory critical absence modulation.
