Biogas intake pressure and port air swirl optimization to enhance the diesel RCCI engine characteristics for low environmental emissions
Dalha, Ibrahim B.; Koca, Kemal; Said, Mior A.; Rafindadi, Aminu D. (Institution of Chemical Engineers, 2024)Exhaust emission and combustion control in RCCI (reactivity-controlled compression ignition) focused mainly on the direct-injected fuel parameters, urging to investigate the advantages of port-fuel intake parameters. ... -
Convenient Site Selection of a Floating PV Power Plant in Türkiye by using GIS-Fuzzy Analytical Hierarchy Process
Karipoğlu, Fatih; Koca, Kemal; İlbahar, Esra (SPRINGER, 2024)Floating photovoltaics (FPVs) are appearing as a promising and an alternative renewable energy opinion in which PV panels are mounted on foating platforms in order to produce electricity from renewable energy on water ... -
Experimental flow control investigation over suction surface of turbine blade with local surface passive oscillation
Koca, Kemal; Genc, Mustafa Serdar; Veerasamy, Dhamotharan; Ozden, Mustafa (Elsevier, 2022)Impact of the local flexible membrane (LFM) on aerodynamic phenomena including the formation of a laminar separation bubble (LSB) and transition to turbulence was experimentally investigated over the suction surface of a ... -
Investigating the best automatic programming method in predicting the aerodynamic characteristics of wind turbine blade
Arslan, Sibel; Koca, Kemal (PERGAMON-ELSEVIER SCIENCE LTD, 2023)Automatic programming (AP) is a subfield of artificial intelligence (AI) that can automatically generate computer programs and solve complex engineering problems. This paper presents the accuracy of four different AP methods ... -
Investigation of the effect of hidden vortex generator-flap integrated mechanism revealed in low velocities on wind turbine blade flow
Ozden, Mustafa; Genc, Mustafa Serdar; Koca, Kemal (PERGAMON-ELSEVIER SCIENCE, 2023)In this study, the flap and vortex generator (VG) mechanisms which were employed separately in aircraft were used as integrated first in literature. In this mechanism, the flap motion triggered and activated the VGs when ... -
Nuclear energy consumption, energy access and energy poverty: Policy implications for the COP27 and environmental sustainability
Bashir, Muhammad Farhan; Ma, Beiling; Sharif, Arshian; Ao, Tong; Koca, Kemal (ELSEVIER SCI LTD, 2023)The ever-increasing energy resource demand and subsequent environmental challenges mean that policymakers have shifted their focus to nuclear energy to address energy and environmental issues due to its unlimited potential. ... -
Passive Flow Control Application Using Single and Double Vortex Generator on S809 Wind Turbine Airfoil
Koca, Kemal; Ozden, Mustafa; Genc, Mustafa Serdar (MDPI, 2023)The current study is aimed at investigating the influences of vortex generator (VG) applications mounted to the suction and pressure surfaces of the S809 wind turbine airfoil at low Reynolds number flow conditions. Both ... -
Predicting the effects of direct-injected fuels co-powered by high-CO2 biogas on RCCI engine emissions using kinetic mechanisms and multi-objective optimization
Dalha, Ibrahim B.; Koca, Kemal; Said, Mior A.; Rafindadi, Aminu D. (ELSEVIER, 2024)High inert gas content in biogas resulted in poor burning and emissions attributes, though scarcely investigated in reactivity controlled compression ignition (RCCI). Established kinetic mechanisms were combined with ...
