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

    منشور في 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 حسب Barooah, Abinash

    منشور في 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 حسب Sharafi, Masoud

    منشور في 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.…"

    Experimental study of exhaust emissions and performance of a dual fuel IDI diesel engine حسب Badr, O.

    منشور في 1999
    "…Dual fuel engines of the compression ignition type provide an alternative approach for I.C. engines to improve economy, reduce exhaust emissions and achieve a greater power. The present contribution is an experimental investigation to evaluate such a statement using a modified Ricardo E6 indirect injection diesel engine. …"
