This paper describes a new high temperature test facility developed through a collaborative effort between the University of Pittsburgh and the Department of Energy’s National Energy Technology Laboratory (NETL). The scope of this paper will include a description of this experimental test facility and a discussion of some test results collected from a flat plate (Haynes 230) using a single row of fan-shaped film cooling holes. This test specimen has been tested at two different pressures (i.e., 1.3 and 3 bar). The hot gas path flow velocity (i.e., 60 m/s) and the hot gas temperature (i.e., 1300 K) have been maintained as a constant for these tests. At each of these test conditions, five different film cooling blowing ratio conditions have been evaluated, including a condition with no film cooling. The overall cooling effectiveness and the reduction in heat flux for a point near the center of the test sample are reported and discussed.
