Abstract: Present study is a numerical investigation on an annular gas turbine combustor model with the simulation of dump diffuser and annuli. Uniform pressure distribution around the liner is desired for designed flow-split through the liner holes. An attempt has been made to achieve uniform velocity and pressure conditions in the annuli (around the liner) by changing the annuli height thereby changing the outer annulus area-to-inner annulus area ratio. It is found that for the area ratio of 2.56, uniform velocity and constant pressure condition is achieved around the bluff body representing the liner in the combustor model.
