通过实验研究了薄矩形几何结构中的热毛细管-浮力对流组合，重点是热液波不稳定性的产生。对于足够薄的层，可以观察到纯热液波，并且发现如先前的线性稳定性分析所预测的那样是倾斜的（Smith & Davis 1983）。对于较厚的层，发现存在稳定的多胞态和振荡态，但后者不是纯热液波的形式。
Combined thermocapillary–buoyancy convection in a thin rectangular geometry is investigated experimentally, with an emphasis on the generation of hydrothermal-wave instabilities. For sufficiently thin layers, pure hydrothermal waves are observed, and are found to be oblique as predicted by a previous linear-stability analysis (Smith & Davis 1983). For thicker layers, both a steady multicell state and an oscillatory state are found to exist, but the latter is not in the form of a pure hydrothermal wave.
