This PhD project focuses on the computational modelling of liquid-fuelled Rotating Detonation Engines (RDEs) for future gas-turbine applications. Using the University's in-house dynamically adaptive RDE code (AMROC), the researcher will implement two-phase flow and spray combustion modelling to quantify the potential of RDE-based jet engines through massively parallel computational fluid dynamics (CFD) simulations.
In partnership with Rolls-Royce Plc, the project involves incorporating Lagrangian tracking of dispersed droplets, evaporation models, and reduced chemical kinetic mechanisms for hydrocarbon combustion. The research aims to inform the design of prototype RDE combustion chambers that could dramatically increase engine efficiency by utilizing pressure-gain combustion for sustainable aviation fuels.
