Abstract
This study was done to extend database knowledge about the film cooling action at the end of combustor and inlet of turbine. The well-known Brayton cycle plays a key role to get higher engine efficiency in gas turbine engines. But the high temperature of the combustor exit flow creates unpleasant environment. These surroundings lead to a reduction in the expected life of critical parts. There are two separate ways for Gas turbine cooling: internal cooling and external cooling. Film cooling is one of the most effective external cooling methods. In this system, a low temperature thin boundary layer such as buffer zone is formed and attached on the protected surface. In this study, a literature survey was done on the limited surveys that considered the effects of flow structure variations on film cooling, particularly from the first of 21th century.
