Frequently asked questions
What is the Brayton cycle in gas turbines?
The Brayton cycle is the thermodynamic cycle used by gas turbines, consisting of compression, combustion, expansion, and heat rejection processes to convert fuel energy into mechanical work.
How does compression ratio affect turbine efficiency?
Higher compression ratios generally increase thermal efficiency up to an optimal point, but also increase compressor work requirements and may reduce net power output if pushed too high.
What's the difference between simple and complex Brayton cycles?
Simple cycles have one compressor and turbine stage, while complex cycles may include intercooling, reheating, or regeneration to improve efficiency and performance characteristics.
