ABSTRACT

The modelling of the furnace has been divided into two parts. On the one hand, a model describing the

physico-chemical processes which occur within the bed of solid. On the other hand, C.F.D.the topic of this

study, This model must include all the relevant physical phenomena occurring within the gaseous phase

(Turbulence, Chemical species transport and reaction, interaction between turbulence and combustion,

radiative heat transfer).

This work is a contribution to the numerical study of axisymmetric turbulent jets (burner CH4) reactive

fluids using (R.A.N.S) approach, in industrial furnace. The modelling of combustion is based on the

model of Magnussen. Turbulence effects are taken in account using the k-ε model .In the case of the

reactive jet, interesting result were obtained concerning the field of temperature, velocity and mass

fractions of the various species,noxious gas pollutant probleme source.
