Abstract
Experimental results are presented which describe the development and
structure of flow downstream of a single row and two staggered rows of filmcooling
holes with compound angle orientations. With the configuration studied,
holes are inclined at 90 degrees with respect to the test surface when projected
into the streamwise/normal plane, and 30 degrees with respect to the test surface
when projected into the spanwise/normal plane. Within each row, holes are
spaced 6.0 hole diameter apart in the spanwise direction which gives 3.0d spacing
between adjacent holes for the staggered row arrangement. Also presented are
plots showing the streamwise development of injectant distributions and
streamwise development of mean velocity distributions.
