Abstract: The objective of the present investigation is to analyse the non-reacting and reacting flow inside a gas turbine engine afterburner. The geometry consists of a diffuser with struts, a V-gutter for flame stabilisation, a combustion chamber and a C-D nozzle. Finite volume method-based software is used. Considering the geometrical symmetry of the configuration, a 180° sector is considered for analysis. The turbulence has been modelled using the RNG version of the k-ε model and the presumed PDF model is used for reacting flow. The influence of the V-gutter location and variations of the core inlet mass flow rate are examined for the non-reacting flow case. The influence of air-fuel ratio is examined for the reacting flow case.
