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

    Published 2024
    “…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. …”

    Understanding the Scales Formation Inhibition Mechanism on C-Steel in a Sour Media by Al-Qahtani, Noora

    Published 2019
    “…In this work, the electrochemical behaviour of C-steel in sour (i) de-ionised water (DIW) and (ii) in different NaCl solutions were examined in an H2S system. A series of experiments were conducted at ambient (RT), 50 oC and at 80 oC using different combinations of inhibitors (A and B). …”

    Sorption of benzene and naphthalene on (semi)-arid coastal soil as a function of salinity and temperature by NgueleuS.K.

    Published 2018
    “…The sorption of naphthalene was not affected by the change in salinity but increased by 18% when the temperature decreased from 35 to 5C. A sorption kinetic model was also applied to define the sorption behavior of benzene and naphthalene for the coastal soil collected in Qatar and the best fits were achieved with the Langmuir sorption isotherm.…”

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

    Published 2014
    “…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.…”
