Abstract
A finite rate chemistry solver usually consumes the largest part of the computing time in the numerical simulation of reactive flows. To reduce these costs, a global simulation method has been developed for systematically simplifying detailed reaction mechanisms and a reduced reaction mechanism for CH4−O2 is presented. This reduced mechanism accurately replicates the associated detailed mechanism whilst significantly reducing the required computing time. A shock induced methane combustion problem is computed by coupling the reduced reaction mechanism to a 1-D viscous compressible flow solver. As a comparison, a simulation of non-reactive shock flow having the same initial conditions is also performed. These calculations reveal some of the key features found in reactive shock flows.
