The film cooling technique is one of the most useful cooling methods. At present, the midchord region of gas turbine blades in an aeroengine often adopt a sparse film cooling technique and impingement cooling technique at the same time. So the interior heat transfer characteristics on the inner side

Five computer programs are used to calculate heat transfer rates to gas turbine blades and the results compared with experimental work on blade cascades. The programs use different methods to model the turbulence quantities. The experimental work was carried out recently in the University of Oxford
Film cooling of a symmetrical turbine-blade model by lateral and non-lateral injection from one row of holes placed on each side near the leading edge is calculated with a 3D ยฎnite-volume method on multi-block grids. For various blowing rates, the ยฏow and temperature ยฎelds are predicted, and in part
