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

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.Validerat; 20101217 (root
