The accurate prediction of local turbine blade temperatures is necessary for the design of cooled turbines. When current methods of predicting blade temperatures are applied to cooled turbine blades, discrepancies between calculated and measured temperatures in some blade leading and trailing sections result. In an effort to reduce these discrepancies and hence to improve blade-temperature predictions, an investigation was conducted for stationary turbine blades with 10 tubes and 13 fins forming the internal heat-transfer surfaces.
