Abstract
Modern gas turbines operate in very demanding thermo-mechanical 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, micro-cooling and the impact of recent applications of additive manufacturing.
