The control and maintenance of desired flow patterns in bends of different orientations (2016)
Journal Article
Zhao, D., Omar, R., Abdulkadir, M., Abdulkareem, L. A., Azzi, A., Saidj, F., …Azzopardi, B. J. (in press). The control and maintenance of desired flow patterns in bends of different orientations. Flow Measurement and Instrumentation, 53(B), https://doi.org/10.1016/j.flowmeasinst.2016.09.003

Multiphase flows are common in industrial settings and bends in pipe lines cannot be avoided due to space limitations. Gas-liquid two phase flows could form material discontinuities that could have adverse effect on productivity and the pipe network...
