The magnitude of the temperature increase as a result of compression heating during the starting process of a high Reynolds number film cooling experiment was more than initially anticipated, creating a mismatch in the design conditions. A review of the time-accurate data showed that two fluid mechanisms, ingestion into the cooling holes during the starting process and compression heating were the causes of the problem, but in different amounts based on the experimental apparatus and time scales involved. The goal of this thesis is to use one of the facilities, the Small Calibration Facility, in conjunction with an analytical model developed for this task to determine how to properly change the start procedure to rectify the problem. The solution to the problem involved adding extra cooling mass at specific times. Several methods attempted, and this particular approach yielded excellent results. In addition, the rework of the start-up procedure allowed for better tuning of the blowdown facility, which resulted in a more constant blowing ratio throughout the experiment.
