    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). …”

    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. …”

    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.…”
