Unsteady Temperature Field in a Turbine Blade Cooling Channel

摘要

The unsteady velocity and temperature fields are measured in a straight smooth and rib roughened square duct, representative of a stator cooling channel. The mainstream Reynolds number is 3 10(4). Single cold and hot wire probes as well as a dual hot/cold wire probe are used for this purpose. The experimental results are compared to the predictions from FINE, a commercial software package developed by Numeca International. This research work was performed while the second and third author were in residence at the von Karman Institute.
