| contents | This study examines the effect of centre-body geometry on the dynamics of an isothermal, non-reacting swirl combustor through computational fluid dynamics (CFD) simulations. Two different central body shapes were considered in a lab-scale combustor configuration, modelled as transient, incompressible flow using the SST k-omega turbulence model. The numerical model was validated against experimental velocity data from literature to ensure accuracy. Cross-spectral analysis techniques were employed to characterise the coherent dynamics of the flow, providing insight into the influence of geometry on unsteady swirl dynamics. |
