Gas Turbine Combustor Effusion Cooling Heat Transfer

The effusion cooling project is an ongoing research effort in the Combustion and Gas Dynamics Laboratory (CGDL) at the University of Connecticut. This project is experimentally-focused, and seeks to quantify the heat transfer characteristics of effusion cooling designs for combustor linings in gas turbine engines. This involves the use of a test section placed downstream from a swirl burner and transition section, which adequately simulates the high thermal stresses inside a typical aero-engine combustor. Within the test section is an effusion test plate, as well as an inlet for the coolant, which in this case is carbon dioxide at specified blowing ratios. Several metrics such as hole angle, spacing, internal contraction, diameter, and coatings can be changed from one design to another. Two optical methods are used to quantify heat transfer characteristics: IR Thermography & Laser Rayleigh Scattering (LRS), and ME72 focuses on IR Thermography to gather information on cooling effectiveness of designs.
