CFD-ACE+ and MALT2 software packages were used in the present calculation.
Simulation Method A numerical simulation was carried out in three steps as follows.
Commercially available software CFD-ACE+ (http://www.esi-group.com/ SimulationSoftware/CFD_ACE/ ) was used under a two dimensional model.
But the surface reaction cannot be solved in the equilibrium reaction model by CFD-ACE+ and thus we tried to use the gas phase reaction model.
