    Experimental and numerical investigation of pyrolysis of municipal solid waste with using computational fluid dynamics
    (TUBITAK, 2021) Polat, F.; Kilinçel, M.; Toklu, E.
    In this study, experiments have been carried out to investigate the effect of temperature on the final product yield of pyrolysis of municipal solid waste. Also, the rotary kiln is numerically modeled, mass, energy, and momentum equations are derived. At the same time, a finite element model was constructed for a pyrolysis reactor designed at three different aspect ratios. A total of 81 computational fluids dynamics analyzes were carried out by using different values for inlet temperature, particle size, and rotation speed with data from Kocaeli province environmental situation report' 2015. According to the analysis conditions, where the maximum methane gas yield is obtained, the energy potential that can be obtained from the municipal solid wastes was calculated. It has been observed that the experimental data overlaps with the analysis in terms of methane yield. © 2021, TUBITAK. All rights reserved.

    A new analysis of two phase flow on hydrogen production from water electrolysis
    (Elsevier Ltd, 2021) Coskun, Avci, A.; Toklu, E.
    It is clear that the entire world have to research, develop, demonstrate and plan for alternative energy systems for shorter term and also longer term. As a clean energy carrier, hydrogen has become increasingly important. It owes its prestige to the increase within the energy costs as a result of the equivocalness in the future availability. Two phase flow and hydrogen gas flow dynamics effect on performance of water electrolysis. Hydrogen bubbles are recognized to influence energy and mass transfer in gas-evolving electrodes. The movement of hydrogen bubbles on the electrodes in alkaline electrolysis is known to affect the reaction efficiency. Within the scope of this research, a physical modeling for the alkaline electrolysis is determined and the studies about the two-phase flow model are carried out for this model. Internal and external forces acting on the resulting bubbles are also determined. In this research, the analytical solution of two-phase flow analysis of hydrogen in the electrolysis is analyzed. © 2021 Hydrogen Energy Publications LLC
