Abstrakt

A method permitting the simultaneous determination of the heat transfer coefficient and adiabatic wall effectiveness for film cooled surfaces has been developed.

The swollen polymer technique, together with laser holographic interferometry, is employed in measuring the mass transfer from a film cooled surface, and the heat transfer coefficient and effectiveness are deduced through the heat-mass transfer analogy.

A tangential slot injection geometry has been used in demonstrating the potential of the method for the rapid acquisition of comprehensive heat transfer data on film cooled surfaces.
