  • Simulations were carried out to investigate the difference of film cooling effectiveness distribution at different blade heights under different blowing ratios and rotational Reynolds numbers. Five cylindrical holes with a diameter of 0.8 mm were located at 17.8% streamwise location and at 10%, 30%, 50%, 70% and 90% blade height, respectively. The study was conducted under three rotational speeds of 400 , 600 r/min and 800 r/min, correspondingly to rotational Reynolds numbers of 357 000, 536 000 and 715 000, respectively. Five blowing ratios of 0.50, 0.75, 1.00, 1.25 and 1.50 were involved. Results showed that film trajectories in the near hub region were deflected a lot toward the tip under the effect of passage vortex. The distribution of film cooling effectiveness at different blade heights was different. Under the effect of centrifugal force and Coriolis force caused by rotation, the increase of blow ratio and rotating Reynolds number yielded different effects on film deflection at different blade heights. The effect of rotational Reynolds number on film cooling at different blade heights was different.
