Numerical and Experimental Study of Flow Dynamics in a Gas Turbine Combustor with Swirl Cup
In arbitrary curvilinear coordinates, numerical investigations of 3D non-reacting and two-phase reacting integrated flow fields for an annular combustor with the swirl cup are carried out. RNG k-ε model, EBU-Arrhenius turbulent combustion model and Six-flux radiation model are used for turbulent combustion. The particle trajectory model is applied to predicting two-phase flows. For verifying mathematical models and numerical methods, the Particle Imaging Velocimetry (PIV) is employed to measure non-reacting and reacting flow fields and the multiple-point thermocouple probe is used to obtain the radial profiles of the exit gas temperature. Predictions are in good agreement with the experimental data. It is shown that the numerical procedures are reasonable and the present research may be used for guiding the improving design of advanced annular combustors.
