    Computational Simulation Of Organic Rankine Cycle Retrofitted To Petroleum Well حسب Kharseh, Mohamad

    منشور في 2014
    "…The obtained results can be used to define the optimal working parameters those result in the maximum energy generation during the lifetime of an organic Rankine cycle retrofitted to petroleum well. As shown in Figure 2, the simulations show that the optimal extraction rate 350 W at temperature difference between inlet and outlet of the well equals 16 oC and ground heat exchanger diameter equals 95 mm. …"

    Enhancing the production of biogas through anaerobic co-digestion of agricultural waste and chemical pre-treatments حسب Almomani F.

    منشور في 2020
    "…The results revealed that the highest cumulative methane production (CMP) of 297.99 NL/kgVS can be generated by co-digestion of ASWs and CD at a ratio of 60:40. Further improvement was achieved via alkalinity treatment with 1.0 g of NaHCO3/gVS leading to decrease in lignin, cellulose, and hemicellulose contents of feedstock by 3.5%, 10.5% and 15.9%, respectively, converting them to soluble fractions and improving the CMP by 11.2–29.7% based on substrate quality. …"

    Study of performance, combustion, and emissions parameters of DI-diesel engine fueled with algae biodiesel/diesel/n-pentane blends حسب Elkelawy, Medhat

    منشور في 2021
    "…Due to the disadvantages of using pure biodiesel in engines, it was used as B50 (a blend of 50% diesel and 50% biodiesel). To enhance engine performance, n-pentane was used in different extents of 5, 10, and 15 ml per liter as an enhancer additive. …"
