...% with a reduction in row 1 of less than 25%. At high downstream MFRs, increasing the density ratio delayed liftoff and increased film cooling effectiveness in row 2 by 65%. However, at low MFRs, increasing the density ratio reduced film cooling effectiveness in row 2 by 60%. endwall film cooling heat...

... 23 02 2010 This paper presents endwall film cooling investigations with a single row of fanshaped holes in a low-speed, six-bladed linear cascade. The variation of the cascade loading was achieved by changing the incidence. The investigated profile is based on a nozzle guide vane...

... 04 08 2009 Endwall film cooling has been subject to many investigations over the past years. Since the coolant is injected into the wall boundary layer, it is primarily affected by the complex three-dimensional flow structure which is developed near the endwall inside turbine bladings...
