Frequently asked questions
What is the Brayton cycle in gas turbines?
The Brayton cycle is the thermodynamic cycle used by gas turbines, consisting of isentropic compression, constant pressure heat addition, isentropic expansion, and constant pressure heat rejection processes.
How does pressure ratio affect turbine efficiency?
Higher pressure ratios generally increase thermal efficiency up to an optimal point, but also increase compressor work requirements and operating temperatures, requiring careful balance for maximum performance.
What factors limit gas turbine efficiency?
Real-world factors include compressor and turbine inefficiencies, pressure losses, heat transfer losses, and material temperature limits that prevent achieving ideal Brayton cycle performance.
