为了研究0.65cSt硅油液层蒸发引起的Marangoni对流不稳定性，在一个矩形开口水池中进行了一系列实验。分析了侧壁温度和环境温度对BM对流与热毛细对流竞争的影响。侧壁温度的升高将不可避免地增强热毛细对流，并通过将热流体从边界转移到表面来抑制BM胞的形成。只要侧壁温度足够高，BM细胞将完全消失，整个层内将出现多细胞卷和水热波。环境温度的升高对BM对流和热毛细对流都有促进作用，但热毛细对流对BM对流的促进作用更大，因为热液波可以在较低的温度下发生。得到了不同环境温度下热液波发生和BM对流单体消失的临界Marangoni数。
In order to investigate the Marangoni convection instability of 0.65cSt silicone oil induced by evaporation in liquid layer, a series of experiments are carried out in an open rectangular pool. The effects of side wall temperature as well as ambient temperature on competitions between BM convection and thermocapillary convection are analyzed thoroughly. Increasing of the side wall temperature would inevitably enhance thermocapillary convection and suppress the formation of BM cells by transferring hot fluid from border to surface. As long as the side wall temperature is high enough, BM cells would disappear completely and multicellular rolls as well as hydrothermal waves would occur in the whole layer. Increasing ambient temperature would enhance both BM convection and thermocapillary convection, but the later one benefits more from it because hydrothermal waves can occur at a lowerManumber. Critical Marangoni numbers for the incipience of hydrothermal waves and that disappearance of BM convection cells are obtained under different ambient temperatures.
