The paper deals with the experimental study of the gas (nitrogen) driven rivulet flow regimes of water outflowing from the nozzle with a width of 10 mm into minichannel with the height of 1.6±0.02 mm and a width of 30 mm. The authors revealed a new flow regime – namely “rivulet bridge” whose occurrence is attributed to the influence of relatively large static wetting angle of water on the flow regimes. The paper presents a map of the various rivulet flow regimes characterized by different surface geometry and types of surface deformations.
