三维界面波在降膜的自由表面上发展，可以强化传热传质。在这种情况下，本文研究了电介质液体的降膜上的静电以及热毛细力的影响。因此，使用共焦彩色成像方法的局部膜厚度的测量在等温和加热条件下进行。实验结果表明，这两种力都使流动不稳定。据发现，在加热条件下的附加电场的应用增强了细流的产生，从而降低了整体传热系数。
Three-dimensional interfacial waves developing on the free surface of falling liquid films are known to intensify heat and mass transfer. In this context, the present paper studies the effect of electrostatic as well as of thermo-capillary forces on a falling film of a dielectric liquid. Therefore, measurements of the local film thickness using a confocal chromatic imaging method were performed under isothermal and heated conditions. The experimental results show that both forces destabilize the flow. It is found, that the application of an additional electric field under heating conditions enhances the generation of rivulets, thereby reducing the overall heat transfer coefficient.
