Abstract: Abstract To allow further increase in gas turbine efficiency, engine core temperatures need to exceed the natural capabilities of metals, necessitating state-of-the-art cooling technologies, such as double-wall transpiration cooling systems. Despite these systems offer excellent… read more here.
