At a glance:Ideal Brayton: η = 1 − (1/r_p)^((γ−1)/γ). Complements carnot-cycle and otto-cycle.
Formula
η = 1 − r_p^((1−γ)/γ).
$$\eta = 1 - \frac{1}{r_p^{(\gamma-1)/\gamma}}, \quad \frac{T_2}{T_1} = r_p^{(\gamma-1)/\gamma}$$How to Use
- Enter pressure ratio and γ.
- The tool returns efficiency and ratios.
Case Studies
r_p=10, γ=1.4
η ≈ 0.50.
FAQ
Real vs ideal?
Real cycles lose to compressor/turbine inefficiencies (lower efficiency).
