Detailed Chemistry Modeling of Laminar Diffusion Flames On Parallel Computers

We present a numerical simulation of an axisymmetric, laminar diiusion ame with nite rate chemistry on serial and distributed memory parallel computers. We use the total mass, momentum, energy, and species conservation equations with the compressible Navier-Stokes equations written in vorticity-velocity form. The computational algorithm for solving the resulting nonlinear coupled elliptic partial diierential equations involves damped Newton iterations, Krylov-type linear system solvers, and adaptive mesh reenement. The results presented here are the rst in which a lifted diiusion ame structure is obtained on a nonstaggered grid. The numerical solution is in very good agreement with previous numerical and experimental data.
