Thank you Flyboy and jack action, I have the answers I was looking for. The equations for the brayton cycle are nice but the real question is how would the efficiency of the compressor and turbine stage be affected by the use of helium, and it appears that it is affected enough to warrant...
Yes, it would be in the case of a closed brayton cycle with a heat exchanger instead of a combustion chamber. These systems were studied for power production in spacecraft.
The reason I asked this question in the aerospace engineering forum is that I wanted to know the impact of such a cycle...
Hello everyone,
I was wondering what would the impact be if an existing gas turbine made to run in air at atmospheric pressure was run in an atmosphere of helium (let's say in a closed loop heated through a heat exchanger). How would the power output and efficiency be impacted, and what would...
