Review of stiffness and implicit finite difference methods in combustion modeling

License(s):

Other (Open)

Stiffness is a mathematical characteristic which is exhibited in combustion models when some components of their solutions respond quickly to system perturbations whereas others respond slowly. This paper presents a physical interpretation of stiffness in chemical kinetics modeling. Implicit finite difference methods are known to be effective in finding solutions to stiff problems, and we present here a general overview of the mathematical concepts important to the implementation of implicit methods.
