Effect of mass flow rates in fuel reactor of chemical looping combustion system

Chemical looping combustion (CLC) is the novel process for increasing thermal efficiency by capturing carbon contents and no NOx generation. In recent research work, bubble hydrodynamics is analyzed numerically in the fuel reactor of the CLC system. User-Defined Function (UDF) is utilized for numerical analysis to analyze the reaction kinetics of fuel reactor. The phenomenon of bubble hydrodynamics is visualized by considering Copper oxide as metal oxide particles in the combustion system and analyzing the molar fraction of the solid-gas fraction of the fuel reactor. For recent research work, the authors have selected various mass flow rates varying from 0.01 kg/s to 0.1 kg/s. The fuel conversion rate increases for mass flow rates between 0.01 kg/s to 0.03 kg/s, but the conversion rate decreases gradually for other mass flow rates beyond 0.03 kg/s.
