Design of a test facility aimed for measurement of gas
turbine vane film cooling effectiveness

Abstract: A test facility to examine the beneficial effects of film cooling has been
designed and built. The test facility test section is made to resemble a
modern first stage guide vane. The rig was design to make use of a
transient infrared thermography test were the time history of the object
under the assumption of a semi-infinite body is assumed. This allows the
simultaneous determination of both the heat transfer coefficient and the
adiabatic wall effectiveness from a single experiment.
