This book was released on 1991 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. In general, for a given m, for all the configurations tested, effectiveness is greatest at low x/d values, and decreases with increasing x/d. As blowing ratio increases, effectiveness generally decreases, particularly at low x/d values because of lift-off effects. Iso-energetic Stanton number ratios vary between 1. 0 and 1.25 for all cases, and generally increase with increasing blowing ratio at any given x/d. Effectiveness values measured downstream of two rows of holes are higher than values measured downstream of one row of holes. Adiabatic film- cooling effectiveness data for both the compound angle injection system and the simple angle injection collapse with minimal scatter in n/m vs xI/s coordinates.

Book excerpt: Experimental results are presented which describe the development and structure of flow downstream of one row and downstream of two staggered rows of film cooling holes with compound angle orientations. Results presented include distributions of iso-energetic Stanton number ratios, and adiabatic film-cooling effectiveness deduced from Stanton numbers using superposition. Also presented are plots showing the streamwise development of injectant distributions and streamwise development of mean velocity distributions. Spanwise averaged values of the adiabatic film-cooling effectiveness are highest for blowing ratio m=0.5 and decrease as blowing ratio increases for x/d less than 20. At farther downstream positions, spanwise averaged effectiveness values increase with blowing ratio, except for data obtained downstream of two rows of holes with a blowing ratio of 3.0 and data obtained downstream of two rows of holes with a blowing ratio of 3.0 and data obtained downstream of one row of holes with a blowing ratio of 4.0, where severe lift-off of injectant occurs. Spanwise averaged iso-energetic Stanton number ratios range between 1.0 and 1.4 and show little variation as x/d increases for each value of blowing ratio, however for each x/d, values increases with increasing blowing ratio. The need for greater efficiency in gas turbine engines has resulted in higher turbine inlet temperatures approaching 2000 K. These extreme temperatures, in combination with the high rotational speeds, result in large stress magnitudes on component materials, especially on the blades of the first turbine stage.
