| Abstract | The effects of phase change on the stability of a horizontally heated liquid layer are studied experimentally in this paper. Results are obtained for two volatile liquids with similar Prandtl numbers in a rectangular geometry with different temperature differences. Three different flow states occur with the variation of the liquid depth, namely oscillating multicellular convection, hydrothermal waves and steady flow. The critical conditions for the transition between the different flow states are identified and discussed. In addition, the presence of evaporation at the interface plays an essential role in the flow instabilities. The results show that evaporation at the surface and associated surface deformation tend to inhibit the development of a hydrothermal wave but conversely promote the transition of oscillating multicellular convection. Furthermore, the transient nature of HTWs is shown to be little affected by the phase change. |
