Numerical Analysis of the Characteristic Chemical Timescale of a C<sub>2</sub>H<sub>4</sub>/O<sub>2</sub> Non-Premixed Rotating Detonation Engine

Numerical Analysis of the Characteristic Chemical Timescale of a C<sub>2</sub>H<sub>4</sub>/O<sub>2</sub> Non-Premixed Rotating Detonation Engine

A three-dimensional numerical investigation using ethylene–oxygen was conducted to examine the characteristics of detonation waves in a non-premixed rotating detonation engine (RDE) across three equivalence ratio conditions: fuel-lean, stoichiometric, and fuel-rich. The study aims to identify the di...
