The mathematical model describing combustion

fluid flow and heat transfer in combustion and carbonization chambers of coke oven was established to describe coupled transport phenomena in complex structures of chambers. Since it is time-consuming and difficult to converge for coupling numerical simulation

two different decoupling numerical methods were proposed and performed. It turned out that two decoupling simulation methods are less time-consuming

easier to be carried out with a good accuracy and a faster convergence compared with coupling method. The second decoupling method is preferred to the first one because of its results’ better match of the actual condition

although it is more time-consuming. It is expected that these two decoupling numerical methods could supply alternative ways for numerical simulation of transport phenomena in combustion and carbonization chambers of coke oven

and be helpful for other similar simulations of complicated transport processes.
