OPPDIF: A Fortran program for computing opposed-flow diffusion flames

摘要: OPPDIF is a Fortran program that computes the diffusion flame between two opposing nozzles. A similarity transformation reduces two-dimensional axisymmetric flow field to one-dimensional problem. Assuming radial component of velocity linear in radius, dependent variables become functions axial direction only. solves for temperature, species mass fractions, and components, pressure gradient, which an eigenvalue The TWOPNT software two-point boundary value problem steady-state form discretized equations.
