This paper presents a physical model of rivulet flow; the shape of the rivulet is determined only by the surface tension (the authors neglect gravity). The rivulet is represented in the form of a segment of a circle which does not vary during the entire flow. All the physical properties of the liquid remain constant and the rivulet moves uniformly in one direction under the action of gravity. The flow is taken as fully developed and steady and shear stresses at the interface are absent. The adopted physical model and coordinate system are shown. The velocity distribution in rivulets was investigated experimentally using a laser Doppler velocity meter.
