“…This presented a particular difficulty: examination of the experimental data pointed out the systematic presence of an interface level gradient (ILG), i. e. the measured interfaces all had a slight downward slope of about a tenth of degree. This ILG is a phenomenon described and explained by Bishop and Deshpande [9]. According to them, the variation of channel resistance in a non-established flow is balanced by a gradual variation of the interface level.…”

A horizontal co-current stratified two-phase flow was studied in a duct with a rectangular section. Its dimensions were such that the top and side walls did not influence the interfacial waves. The film thickness was almost of the millimeter. The Reynolds number based on the mean height and velocity in each phase varied from 0 to 1.16•10 5 in air and from 69 to 271 in water. These experimental conditions allowed the observation of the smooth, 2-D wavy and 3-D wavy stratified flow patterns. The interfacial waves were instantaneously measured on a 100 mm long line segment in the longitudinal midspan plane of the channel with the Level Detection and Recording technique. These measurements yielded statistical characteristics and highlighted the spectral differences between the 2-D and 3-D wavy stratified flow patterns.

“…The agreement between the observed patterns and the flow map is poor, partly because the authors heavily relied on pipes of round section to establish their map. It is also known that the transition from smooth to wavy stratified is sensitive to inlet conditions and to the presence of an ILG (see [9]), it is thus difficult to predict.…”
