Theoretical and experimental investigations have been carried out concerning the influence of mass flow rate on the rivulet contact angle and further on the surface area wetted by the rivulet. Presented results clearly inducate the existence of four distinct regions with respect to the contact angle and the rivulet width. Theoretical models have been proposed for three of the regions. For the second and third regions a relevant correlation has been developed for rivulet width and presented together with the experimental data of some other authors.
