Abstract
The experimental technique of film cooling using a Ludwieg tube wind tunnel is reported. The main airflow is produced behind expansion waves, and the secondary flow from a pressurized tank is injected into the main-flow boundary layer through two staggered rows of holes. The combined short-duration flow reaches a steady state in a specially designed test section after a starting period of several milliseconds. Heat transfer measurements are conducted on a constant wall temperature boundary condition in both streamwise and spanwise directions using miniature platinum thin-film heat flux gauges constructed by the authors. From measured data, the film cooling effectiveness and the heat transfer coefficient are determined simultaneously. Test results compare well with those obtained from continuous wind tunnel experiments.
