Abstract : The DoD Grant (No. F4962O-93-1) has been used to significantly expand and upgrade the capabilities of the facilities and instrumentation used by projects supported by AFOSR Grant No. F49620-94-0126 and by DoD EPSCoR fellowship grant No. F49620-92-J-0459. These two projects focus on experimental studies for flow and thermal structures in the hot flow passage in gas turbines. A summary of the expenditures has been included. Some changes were made from the original budget, and the details of these changes have been provided. Several custom-manufactured probes were specifically designed for measuring heat transfer and fluid flow structures within transitional boundary layers. The preliminary results were able to resolve the controversial issue regarding the negative value of cross-stream Reynolds beat flux (vt) in a transitional boundary layer. The expanded capability of the instrumentation also benefited research on the Advanced Turbine Systems project sponsored by the Department of Energy and on heat transfer enhancement using micro-structured surfaces sponsored by the 3M Company.
