Abstract

An accurate Navier-Stokes solver is developed that includes a flame sheet model for the combustion reactions and a simple model for the formation of soot. The flame sheet model is applicable to compressible flows at subsonic Mach numbers and requires three scalar variables to determine the local thermodynamic state: Mixture fraction, density and internal energy. A dimensionless form of the pdes is established that allows passage to the limit of zero Mach numbers without singularities. The numerical solution method is based on accurate finite difference operators and Runge-Kutta type time integrators. The solver is applied to axi-symmetric non-premixed ethylene flames.
