  Full Text
A method is presented for rigorously controlling the errors introduced by using reduced chemistry models in reacting flow simulations. The method is demonstrated in an Adaptive Chemistry simulation of a simple 1-D laminar premixed methane/air flame. The results are compared with the results of the same calculation performed using the full chemistry model. The Adaptive Chemistry solution satisfies the predicted error criteria.
