Alternate cooling configurations for gas turbine combustion systems
Abstract
Work aimed at the synthesis, characterization, and evaluation of several alternate types of advanced wall cooling schemes is reviewed -- specifically, film-convection cooling, laminated porous wall cooling, and angled, multihole (effusion) cooling. The concept definition, heat transfer performance characterization, and design problems associated with each basic concept are reviewed, and relevant rig and engine experience cited. A brief assessment of the structural limitations of the several cooling schemes is also made, together with a review of the key materials and fabrication considerations.
