OPPDIF: A Fortran program for computing opposedflow diffusion flames
Abstract
OPPDIF is a Fortran program that computes the diffusion flame between two opposing nozzles. A similarity transformation reduces the twodimensional axisymmetric flow field to a onedimensional problem. Assuming that the radial component of velocity is linear in radius, the dependent variables become functions of the axial direction only. OPPDIF solves for the temperature, species mass fractions, axial and radial velocity components, and radial pressure gradient, which is an eigenvalue in the problem. The TWOPNT software solves the twopoint boundary value problem for the steadystate form of the discretized equations. The CHEMKIN package evaluates chemical reaction rates and thermodynamic and transport properties.
