This presentation will discuss the use of systematically reduced
mechanisms in high-temperature combustion. These reduced mechanisms
are derived from detailed mechanisms through the successive
application of the quasi-steady-state approximation. The advantages
and disadvantages of such an approach will be discussed as will
several topics related to the development of reduced mechanisms.
One important topic is the degree of reduction possible for
modeling various phenomena. This determines the range of applicability
of the mechanism and the degree of computational effort required
for a solution.
Another important topic is the algorithm for the development
of the reduced mechanism through the identification of the steady-state
species. While this MAY be done by analytic means, it is a relatively
difficult problem and physical or chemical intuition will still
play an important role.
