A combustor liner for a combustor of a turbine engine, comprising: a generally cylindrical liner that extends from a head end to an aft end; a venturi formed in an interior of the liner between the head end and the aft end, the venturi being formed by: a first inclined portion of the liner that reduces in diameter while progressing in the aft direction; and a second inclined portion of the liner that increases in diameter while progressing in the aft direction, wherein an aft end of the first inclined portion is joined to a head end of the second inclined portion; and an air deflector that is mounted on an exterior of the liner such that it at least partially surrounds at least one of the first and second inclined portions and such that an annular space is formed between an inner side of the air deflector and an outer side of the liner, wherein the air deflector is configured to deflect a portion of a flow of air that is passing along the exterior of the liner from the aft end to the head end onto a circumferential depression formed on an exterior the of the liner by outer sides of the first and second inclined portions, and wherein air passing through the annular space continues to travel along the exterior of the liner toward the head end of the liner where it turns 180° and enters the interior of the combustor liner.
