Résumé :
|
Two low-aspects-ratio trapezoidal test section geometries, simulating the trailing edge cooling cavities of turbine blades, roughened with seven different turbulator geometries, were tested for heat transfer and pressure variations. The test sections were tested both with and without bleed holes.
