Velocity distribution has been measured in the outer annulus for two inlet conditions and the flow split through dilution, primary and cooling holes have been evaluated. It is observed that the flow split through the turn-section rows of cooling holes as well as swirlers and the inner annulus does not get affected significantly by the change in the inlet conditions
