Influences of swirler parameters for a single annular concentric staged(SACS) combustor on non-reacting flow field in the SACS combustor were investigated computationally using standard k-εmodel.The computational results indicate that
the influences of swirling directions of the pilot swirlers on the flow field in the SACS combustor are insignificant.Influences of outer swirler on the flow field in the SACS combustor are significant when the vane angles of the three swirlers in the SACS are adjusted.Therefore
the outer swirler is a key factor to the flow structure forming in the SACS combustor.
