A higher-order projection method for the simulation of unsteady turbulent nonpremixed combustion in an industrial burner

摘要

We introduce a new methodology for the modeling of unsteady, nonpremixed, reacting flow in industrial burners which is based on a higher-order projection method for the equations of low-Mach number combustion. The time step used by the method is restricted solely by an advective CFL condition. The method uses standard submodels to account for turbulent transport, kinetics, and radiative transport. The method is presented in the contest of axisymmetric flow with swirl in burners with simple boundaries. Numerical results from a sample problem are shown.
