A barbeque grill assembly having a cooking chamber includes a liquid reservoir, a first grilling member supported above the reservoir, the first grilling member including a foraminous planar element on which food to be grilled is arranged, a cylindrical stack arranged centrally of the reservoir, and a cover disposed over the reservoir, the first grilling member and the stack. At least one of the cover and the stack includes an air flow impacting member for radially dispersing warmed air throughout the cooking chamber. A heat source is disposed beneath the liquid reservoir, and the stack communicates air heated by the heat source with the cooking chamber. The stack comprises a tube having a diameter and an elongated longitudinal axis extending from a region adjacent the heat source to a region adjacent the central portion of the cover. The stack includes air swirling means projecting into or towards the conduit formed by the stack. One form of the air swirling means is an array of deformed areas on the stack surface which comprises helically arranged inner wall protuberances projecting into the interior of the stack. To further enhance the swirling of heated air within the cooking chamber, the surface of the cover that overlies the stack may be formed with a conical formation at the central region thereof.
