In this study, numerical calculations acquired to advance toward the optimization of the fuel injection and fluidic stability inside gas turbine combustor. These calculations were performed under unsteady-state condition by using k-ε turbulence model as it has been the most foretelling scheme for modeling swirling flow inside gas turbine combustors. Swirl flow has been employed to the combustor with Methane (CH4) as the primary fuel. CH4 was injected at different inlet flow rates with constant air injection. Four planes were selected to yield an additional comprehension of the vortex breakdown characteristics with different values of frequency. The results presented here are a small and representative sample of the total. Oscillation of the flow of CH4 lead up to acceleration in the free-field of the radial pressure gradient. The pressure gradient changed to the axial direction which provides the vortex breakdown bubble and reverses the flow behavior. The stagnation point relocated due to the change in the state of vortex breakdown and the structure of the swirling flow changed.
