摘要: Abstract This paper presents an experimental investigation of the film cooling performance a hybrid scheme using thermochromic liquid crystal technique. The includes two consecutive hole configurations with interior bending. was analyzed for blowing ratios ranging from 0.5 to 1.5. bending effect this throttles secondary flow causing it spread widely over downstream surfaces, and consequently enhance at both low high ratios. results showed that augmented centerline laterally averaged effectiveness compared other schemes in literature.
