Isothermal compressed air system for internal channel cooling

摘要

The objective of the current experimental study is to build a system that can provide a steady state mass flow rate of air and constant temperature which will be used for cooling system of gas turbine blade. The compressed air is used as air supply for jet impingement in a rotating test model. The system is capable to provide 200 l/min of compressed air at constant temperature for a period of 50 minutes at 4 bar pressure. Three different designs have been tested with different tanks arrangements. Three tanks with total volume of 2 m2 where used to produce the compressed air conditions.
