Abstract
The present gas turbine technology increases the turbine inlet temperature to a limitation which is very high gas temperature accomplished by recently developed material and cooling technology. In order to overcome the limitation and enhance higher thermal efficiency, the multi-scale thermal design technique must be considered in development of modern gas turbines. This study investigates to present a direction of research to overcome the limitation in a course of macro-scale cooling technology, multi-scale thermal measurement/application for precise thermal design, multi-scale thermal analysis/design with aid of micro/nano-scale technology, and thermal reliability and optimal thermal/cooling design technology. This multi-scale thermal design technique will be widely used for vane, blade, and combustor cooling design to develop higher thermal efficiency of modern gas turbines.
