This thesis project consists of the development of a combustion model able to replicate the functioning of a bluff body burner, characterized by a non-premixed flame and run with a mixture of CH4 and H2 (50% by volume), by means of a CFD (Computational Fluid Dynamics) software called CONVERGE. The project is a new starting point in the creation of a reliable model for a real turbine combustor and so enlarge the field of application of the abovementioned software, now mainly used for modelling internal combustion engines. The whole thesis project has been carried out at the CFD company Convergent Science GmbH in Austria and all the experimental data has been provided by the Aerospace, Mechanical and Mechatronic department of the University of Sidney, that has collected them using LDV technique.
