A combustor for use in a turbine engine including a compressor section, a combustion section downstream from the compressor section, and a turbine section downstream from the combustion section. An inner annulus wall extends from a burner end of the combustor to an outlet end of the combustor. An outer annulus wall is disposed outwardly from the inner annulus wall and extends from the burner end of the combustor to the outlet end of the combustor. A passageway is formed between the inner annulus wall and the outer annulus wall and extends from a combustion zone to the outlet end of the combustor. A plurality of symmetrically distributed section walls extends between the inner annulus wall and the outer annulus wall from the burner end of the combustor toward the outlet end of the combustor. The section walls divide the combustion zone into a plurality of segments.
