The greenhouse problem has a significant effect on our communities such as,health and *** dioxide is one of the main gases that cause global ***,CO2 capture techniques have been the focus of attention these *** chemical looping combustion technique adopted the air reactor and fuel reactor to recycle heat *** study presents a numerical and experimental investigation on a fuel reactor in chemical looping combustor(CLC)*** present numerical model is introduced by the kinetic theory of granular flow and coupled with gas–solid flow with chemical reactions to simulate the combustion of solids in the *** k–εturbulent model was used to model the gas phase and the particle *** developed model simplify the prediction of flow patterns,particle velocities,gas velocities,and composition profiles of gas products and the distribution of heterogeneous reaction rates under the same operating *** predicted and experimental results were compared according to the basis of determination coefficient(R2).In addition the results showed that there is a good agreement between the predicted and experimental *** value of(R2)for CO,CO2 and CH4 was 0.959,0.925 and 0.969 *** shows that the present model is a promising simulation for solid particle combustion and gives the power direction for the design and optimization of the CLC systems.
