Review of Turbine Cooling Technologies
Dariusz Olczak, Maciej Jaworski
Abstract
Abstract Modern gas turbines operate in very demanding thermomechanical conditions. The operating temperatures are typically higher than material capability, which requires the parts to be cooled. This work aims to provide a concise overview of the current cooling methods and heat transfer mechanisms occurring in modern gas turbines, including different types of turbulence promoters, impingement, film cooling, microcooling, and the impact of recent applications of additive manufacturing.
