Investigations on Projection-Based Reduced-Order Model Development for Rotating Detonation Engine

What is it about?

Nowadays, high fidelity simulations of rotating detonation engines (RDEs) are computationally expensive for practical engineering applications. This work investigates the development of projection-based reduced order models (ROMs) for high-accuracy but low-cost RDE simulations. Three different ROM methods are investigated and evaluated. Specifically, a newly developed adaptive model order reduction (MOR) formulation has been successfully demonstrated to construct high-fidelity ROMs for the RDE applications with considerable reduction in computational time.
