Multidisciplinary investigation of center body effects on rotating detonation engine

This thesis investigates the modeling and analysis of Rotating Detonation Engines (RDEs), an innovative propulsion technology with potential advantages over conventional engines. The study begins with an introduction to deflagration, detonation, and various RDE configurations, followed by an exploration of detonation cycles. The research employs a comprehensive approach to RDE modeling, encompassing mathematical, thermodynamic, and numerical methodologies. Particular attention is given to balance laws and the application of OpenFOAM solver for computational fluid dynamics simulations. The methodology section details the CFD simulation setup, including mesh generation, boundary conditions, initial conditions, and CPU scaling considerations. A thorough test case analysis is conducted, focusing on standard RDE configurations and stability results. The study examines the stability characteristics of different engine geometries and investigates the physical significance of various modes. Performance analysis is carried out for standard engine geometries and explores the impact of different inner body configurations and aerospike nozzle designs. The research culminates in a comprehensive conclusion, synthesizing the findings from stability and performance analyses. Supplementary stability and performance tables are included to provide additional data support. This work contributes to the growing body of knowledge on RDE technology, offering insights into design optimization and performance enhancement for future propulsion systems.
