    Thermomechanical exergy and thermoeconomic analysis of geothermal district heating systems
    (2008) Ozgener L.; Ozgener O.
    The current paper presents the thermomechanical exergy and thermoeconomic analysis of geothermal district heating systems (GDHSs) in Turkey. The case studies cover the actual system data taken from the systems in Afyon, Gonen, and Salihli GDHSs, Turkey. General energy and exergy analysis of the GDHSs are introduced. Then the analysis applied to these GDHSs using actual thermodynamic data for their performance evaluations in terms of energy and exergy efficiencies are presented. Besides, thermoeconomic evaluations of GDHSs are given in tables. © IMechE 2008.

    Parametric study of the effect of reference state on energy and exergy efficiencies of a small industrial pasta drying process
    (Inderscience Publishers, 2009) Ozgener L.; Ozgener O.
    The paper describes a performance evaluation of the industrial pasta process system in Gaziantep, based in Turkey, on energy and exergy analyses. The case study covers the actual system data taken from the system. General energy and exergy analysis of the system are introduced. This analysis, applied to the system using actual thermodynamic data for its performance evaluation in terms of energy and exergy efficiencies, is presented. In addition a parametric study of the effect of varying reference state properties on the energy and exergy efficiencies of the system has been conducted to find optimum performance and operating conditions, and is explained.

    Modelling and Optimization of Uranium (VI) Ions Adsorption Onto Nano-ZnO/Chitosan Bio-composite Beads with Response Surface Methodology (RSM)
    (Springer New York LLC, 2018) Kaynar Ü.H.; Çınar S.; Çam Kaynar S.; Ayvacıklı M.; Aydemir T.
    Nano-ZnO-chitosan bio-composite beads were prepared for the sorption of UO22+ from aqueous media. The resulting nano-ZnO/CTS bio-composite beads were characterized by TEM, XRD etc. The sorption of UO22+ by bio-composite beads was optimized using RSM. The correlation between four variables was modelled and studied. According to RSM data, correlation coefficients (R2 = 0.99) and probability F-values (F = 2.24 × 10− 10) show that the model fits the experimental data well. Adsorption capacity for nano-ZnO/CTS bio-composite beads was obtained at 148.7 mg/g under optimum conditions. The results indicate that nano-ZnO/CTS bio-composite beads are appropriate for the adsorption of UO22+ ions from aqueous media. Also, the suitability of adsorption values to adsorption isotherms was researched and thermodynamic data were calculated. © 2017, Springer Science+Business Media, LLC.
