CFD+reactor network analysis: an integrated methodology for the modeling and optimisation of industrial systems for energy saving and pollution reduction

An integrated methodology for the simulation of practical combustion systems and NOx prediction was developed. It is based on 3D CFD simulation coupled to a postprocessor which yields reactor networks, extracted from 3D fields, as `equivalentʹ simplified flow models for which it is possible to use a detailed reaction kinetics. A review of some relevant application is presented to illustrate how this methodology can help in design and optimisation of industrial combustion systems towards a comprehensive improvement of the environmental performances.
