Abstract
Experimental results are presented which describe the development and
structure of flow downstream of single and double rows of film-cooling holes
with both simple and compound angle orientations. Two configurations are
investigated, a simple angle injection system in which the injectant is introduced
into the freestream parallel to the main flow (as viewed in streamwise/spanwise
planes), and a compound angle injection system in which the injectant is
introduced with spanwise velocity components. Results indicate that effectiveness
depends mostly on four parameters: simple or compound angle injection,
spanwise hole spacing, one or two rows of holes, and blowing ratio.
