Flow characteristics in the liner of a reverse-flow gas turbine combustor

Investigation carried out in a plane model of a reverse-flow gas turbine co mbustor under isothermal flow conditions has shown that the bulk of the flo w remains close to the outer liner wall between the rows of primary and dil ution holes, while it shifts towards the liner mid-plane after the row of d ilution holes. At the combustor outlet, the bulk of the flow remains toward s the inner wall of the outlet duct, with a uniform flow distribution. At t he outlet of the combustor model, turbulence intensity was approximately th ree times higher than that at the inlet plane.
