Abstract

The objectives of this work is to determine the average rate of reaction by numerical study of the reacting flow inside an axisymmetric free jet, and the validation of the eddy dissipation concept (EDC) combustion model implemented in ANSYS Fluent. The validation of the eddy dissipation concept combustion model involved the reproduction of a lifted, non-premixed, turbulent free jet flame described experimentally in Mahmud (2007). Three chemical mechanisms were used along the combustion model, namely the 2-step Westbrook and Dryer mechanism, the skeletal Jones-Lindstedt mechanism and the Hyer mechanism. Turbulence was modeled with the standard k-ε model The flame lift-off height and the temperature profiles are reproduced accurately by the Hyer model.
