Reynolds number effect on leading edge film effectiveness and heat transfer coefficient Academic Article uri icon

abstract

  • The effect of mainstream Reynolds number on leading edge heat transfer coefficient, film effectiveness, and heat flux was experimentally studied. Data were obtained for several combinations of film hole shapes and spacings, film hole row locations, blowing ratios, and mainstream turbulence levels at the Reynolds numbers of 100000, 40 000, and 25 000. Representative results from 3-d and 4-d spaced two row injections, at the intermediate blowing ratio of 0.8, with and without turbulence grid are presented. Both heat transfer coefficient and film effectiveness increase with Reynolds number. A Reynolds number of 100000 produces the lowest heat flux ratio in most of the leading edge region.
