A novel method has been developed for predicting flow field by a set of physics-based and empirical equations which provide inputs to a chemical reactor networks (CRN) composed of Perfectly Stirred Reactors (PSR) and Plug Flow Reactors (PFR), allowing rapid and reasonable analysis of NOx emissions. The method is applied to a rectangular section of a gas turbine combustor and the simulation results are compared with experimental results. The CRN has been established and successfully validated for baseline operating conditions. This methodology has shown to be efficient for estimating NOx emissions with a short simulation time (few minutes) and small CPU requirements.
