Combustion
Combustion
is of great importance in modern society, as a means of supplying energy for
everyday use, for powering vehicules, and for industrial processes.
Turbulent Combustion occurs frequently : in Internal Combustion (IC) engines, gas turbines, furnaces etc. Premixed Combustion - in which the fuel and oxidant are thoroughly mixed before combustion - is a special limiting case, but modelling can be extended to tackle partially premixed systems as well.
CFD Computational Fluid Dynamics
CFD (computational fluid dynamics) combustion models can be used to:
aid understanding
improve efficiency,
reduce pollutant emissions,
reduce design costs and development times
Modelling Turbulent Combustion
A model for turbulent combustion must represent the turbulence, the combustion, and their interaction. Current approaches include :
Eddy Break-up models : simple but inaccurate
PDF methods : highly complex, difficult to compute
Flame-area models
CFD Database
Our work is aimed at improving the understanding of the processes involved, and providing a database to validate CFD combustion models, espcially for the NO formation depending in the cooling of the flame.
