Abstract

In this paper a new test rig for the characterization of advanced combustor cooling concepts for gas turbine combustors is introduced. The test rig is designed to allow investigations at realistic operating conditions of future lean combustors at elevated pressures and temperatures. The features and capabilities of the test rig in comparison to existing rigs are described. The properties of the hot gas flow are measured in order to provide the necessary data for an detailed analysis of the measured cooling efficiency of combustor wall test samples. Results of the characterization of the velocity and temperature distribution in the hot gas flow at the leading edge of the test sample at pressures up to p=10bar and global flame temperatures up to T=2000K are presented.
