The Effect of Heat Transfer on Turbine Performance
Despite the blades downstream of the combustor being cooled in most large gas turbines, the effect this cooling has on their performance is still unclear. Fundamental questions, such as how turbine efficiency should be defined and which flow features reduce performance, remain unanswered. This thesis answers these questions and addresses the problem of
