Computational fluid dynamics and experiments have been used to study the mixing of multiple jets in a can combustor. An existing configuration having a poor exit temperature profile was chosen as the baseline case. In the computations, the air split and axial location of the primary, secondary and dilution jets were held constant while the number of jets at each location were varied parametrically to determine their effect on the exit temperature profile. As a result of these studies, two configurations were selected for experimental verification of the anticipated improved performance. The modified design was found to have a more uniform exit temperature profile than the baseline case. Thus the experimental results generally confirmed the predictions and demonstrated the potential utility of CFD as a design tool.
