Counterflow premixed laminar flames

The modeling of steady-state problems in combustion and heat and mass transfer can often be reduced to the solution of a system of ordinary or partial differential equations. In many of these systems the governing equations are highly nonlinear and one must employ numerical methods to obtain approximate solutions. The solutions of these problems can also depend upon one or more physical/chemical parameters. For example, the parameters may include the strain rate or the equivalence ratio in a counterflow premixed laminar flame (1-2). In some cases the combustion scientist is interested in knowing how the system mil behave if one or more of these parameters is varied. This information can be obtained by applying a first-order sensitivity analysis to the physical system (3). In other cases, the researcher may want to know how the system actually behaves as the parameters are adjusted. As an example, in the counterflow premixed laminar flame problem, a solution could be obtained for a specified value of the strain...

The code FlameMaster (FlameMaster) is another alternative to the CHEMKIN simulation codes. It is a free computer program for OD combustion and ID laminar flame calculations with local sensitivity analysis. FlameMaster can carry out homogeneous reactor and perfectly stirred reactor calculations, and is able to simulate freely propagating premixed flames and steady counterflow diffusion flames with potential flow or plug flow boundary conditions.
