The animation below shows the interfacial wave structure in circumferential direction of a falling liquid (water) film using Multi-Pin Film Sensor (for more details on experimental setup, see my previous post on the following link):

This animation was taken at liquid Reynolds number, ReL=1670. The inner diameter of the test section is 127 mm. Unlike small diameter pipes where the waves are characterised as coherent rings, the waves found in this study with large diameter pipe are more localized.
