Numerical Simulation Of Turbulence-Radiation Interaction In A Cylindrical Incinerator Of The Smokes Produced By Household Wastes

Abstract A numerical study of the thermal destruction of the pollutant components of smoke generated by wastes combustion is presented. Calculations are performed for a cylindrical incinerator with an inlet and outlet port. Turbulent transfers are modeling using RANS equations and the k-26949 model. These equation linked to the radiative transfer equation are solved using an implicit scheme based on the finite volume method. We analyze the effects of Reynolds number inlet and outlet port position and radiative transfers on the velocity and temperature fields and on the cleaning up of the smokes effectiveness. The results show that the thermo destruction process is more efficient for low Reynolds number. The radiative transfer intensifies transfers in the incinerator and enhances the thermo destruction process efficiency. The cleaning up of the smokes is better with an outlet port position shifted with respect to the inlet port location.
