Abstract: The local Mach number and heat transfer coefficient over the aerofoil surfaces and endwalls of a transonic gas turbine nozzle guide vane have been calculated. The computations were performed ...

Abstract: This paper presents experimental measurements of the performance of a new film-cooling hole geometry—the converging slot-hole or console. This novel, patented geometry has been designed to improve ...

Abstract: This paper presents the first experimental measurements on an engine representative nozzle guide vane, of a new film-cooling hole geometry, a converging slot-hole or console. The patented console ...

Abstract: The influence of surface roughness on heat transfer coefficient and cooling effectiveness for a fully film cooled three-dimensional nozzle guide vane (NGV) has been measured in a transonic annular ...
