How does pressure ratio and intercooling affect gas turbine performance?

AI Thread Summary
Pressure ratio significantly influences gas turbine performance, affecting both thermal efficiency and net work output. Higher pressure ratios generally lead to improved efficiency, but they also impose temperature constraints that must be managed. Two-stage compression with intercooling enhances performance by reducing the work required for compression and minimizing thermal losses. This setup allows for higher pressure ratios without exceeding temperature limits, ultimately improving overall efficiency. Understanding these relationships is crucial for optimizing gas turbine design and operation.

Hey Mech Eng Forum, I'm currently examining the performance on gas turbine and wondering:

How is the performance of gas turbines (Primarily thermal efficiency and net-work output) influenced by the pressure ratio and temperature constraints? Additionally, what is the benefit of 2 stage compression with intercooling?

Thanks!

Welcome to the PF, Roberto. :smile:
 
BTW, this sounds a bit like a schoolwork problem. What is the context of your questions? And what reading have you done on this subject so far? Can you post links to that reading?
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
