| Cycle Type | Combustion Process | Ideal Efficiency | Pressure Gain | |------------|-------------------|------------------|----------------| | Brayton (deflagration) | Constant pressure | ( 1 - \frac1r_p^(\gamma-1)/\gamma ) | None (ΔP < 0) | | Humphrey (detonation) | Constant volume (approx.) | Higher than Brayton at same compression ratio | Yes (ΔP > 0) | rde 317
In RDEs, the detonation wave provides self-compression, reducing or eliminating the need for a mechanical compressor in gas turbines or a turbo pump in rockets. This translates to: Author: [Your Name] Course: RDE 317 – Advanced
The oxidizer and fuel must be injected at high frequencies (kHz) to match wave passage. Premixing is generally avoided due to flashback risk; instead, impinging jets or micro-orifices are used to achieve rapid mixing in ~1–2 mm distance. 0) | In RDEs
