Development of a Mechanistic and Data-Driven Model for Multiphase Flow Leak Detection in Pipeline by Barooah, Abinash

“…The effect of different pressure constraints, pipe length, pipe diameter, two-phase fluid rheology, leak diameter, leak location, outlet liquid volume fraction, and flowing liquid hold-up on leak size, pressure, and flow rate is analyzed. Decreasing the liquid fraction in the outlet section of the leak leads to a slight increase (6% average) in the inlet mass flow rate and a significant decrease (50% average) in the outlet mass flow rate for fixed pressure constraints, resulting in an increased leak flow rate, pressure, and density. …”

A dynamic MOPSO algorithm for multiobjective optimal design of hybrid renewable energy systems by Sharafi, Masoud

“…Additionally, the set coverage metric value shows that at least 67% of Pareto solutions obtained by DMOPSO dominate the solutions resulted by other reported algorithms. By using a sensitivity analysis for the case study, it is found that if the PV panel and wind turbine capital cost are decreased by 50%, the total NPC of the system would be decreased by 18.8 and 3.7%, respectively.…”

Gelation of Emulsified Polyacrylamide/Polyethylenimine under High-Temperature, High-Salinity Conditions: Rheological Investigation by Mohamed, Abdelhalim I. A.

“…It is suggested that the emulsification acts as an insulator, hence heat transfer to the gelant is slow. The elastic (i.e., storage) modulus of the emulsified PAM/PEI increased by about 29% when the temperature was raised from 120 to 150 °C. …”
