INFRARED IMAGING DIAGNOSTICS FOR EFFUSION COOLING EFFECTIVENESS WITH COMPOUND ANGLES
Infrared imaging diagnostics experimental investigations were performed on overall effusion cooling effectiveness of the large-scale effusion flat walls with different hole spacing and compound angles 45° or 90°, and constant inclined angle 30°,for advance gas turbine combustors. Three effusion wall configurations were studied to research the effect of the hole spacing and compound angle. Using the infrared images, the detailed overall cooling effectiveness distributions on the two-dimensional surface were exhibited and analyzed. The optimum configuration designs of effusion cooling wall were obtained for gas turbine combustors, according to the comparison of the experimental results. It was also demonstrated that the infrared technique is an effective and aggressive method to research the detailed cooling effectiveness distribution of cooling wall field.
