...Shahzad Munir; Muhammad Israr Siddiqui; Abdul Rashid bin Abdul Aziz; Morgan Heikal; Umer Farooq Large-scale turbulent flow features in liquid (water) and gas (air) phases in the film region of two-phase slug flow are identified by using proper orthogonal decomposition (POD) of the vorticity fields...

..., 2013. Assoc. Editor: Francine Battaglia. 23 10 2012 22 07 2013 In the present work, the onset and subsequent development of slug flow in horizontal pipes is investigated by solving the transient one-dimensional version of the two-fluid model in a high resolution mesh using a finite...

..., aerators, steep channels, etc. Under certain conditions, air may also be introduced into pressurized intake systems, which may form large bubbles in portions of the pipe. The bubbles may, in turn, cause an unstable slug flow, or other flow patterns, that leads to sever periodic transient pressure...

...-phase flow pattern was mainly slug flow. Based on the experimental data, a correlation for the liquid phase separation is proposed. Finally, the volume-weighted phase separation in the branched elbow was compared with the phase separations on the T-junction, and it was found that in some cases...

..., from stratified to pressurized. Among different patterns, slug is most complex with extreme pressure variations. Due to lack of firm relations between pressure and influential parameters, study of slug flow is very important. Based on an experimental model, pressure fluctuations inside a circular...
