Experimental investigation of the effect of 90° standard elbow on horizontal gas–liquid stratified and annular flow characteristics using dual wire-mesh sensors

Experimental characterization of vertical gas–liquid pipe flow for annular and liquid loading conditions using dual Wire-Mesh Sensor

“…Similarly, in order to avoid disturbances to the flow, the WMS was placed 0.9 m upstream of a standard elbow (r/d = 1.5). More details about the experimental facility can be found in Vieira et al [24].…”

On the characteristics of the roll waves in gas–liquid stratified-wavy flow: A two-dimensional perspective

“…3). The use of dual WMS is for the purpose of the quantification of interfacial structure velocity at given experimental conditions, and is adopted by several other researchers in recent years [23][24][25][26][27][28]. However, the data from the first WMS is used to calculate time-averaged flow quantities such as liquid holdup, liquid film height, wetted wall perimeter and interfacial surface area.…”

Experimental characterization of vertical downward two-phase annular flows using Wire-Mesh Sensor

“…Additional flow visualization analysis can be performed by reconstructing the phases in a three-dimensional fashion, as carried out by Vieira et al, 2014aVieira et al, , 2014b. The iso-surface plots of the air phase in the two-phase flow structures are obtained by fixing the threshold of void fraction to the individual air and liquid phases.…”

“…Gas velocity radial profiles were also obtained by crosscorrelating the void fraction profiles from both modalities. Recently, Vieira et al (2014aVieira et al ( , 2014b used dual Wire-Mesh Sensors to detect the local instantaneous cross-section distribution of the phases in horizontal gas-liquid stratified and annular flow. Data were obtained for a wide range of flow rates and for horizontal pipe orientation.…”
