Characteristics of rotating detonation waves in a hollow chamber with different fuel injection positions

To address the thermal protection challenges associated with the rotating detonation engine (RDE) in engineering applications, this study employs a three-dimensional numerical simulation based on the Eulerian–Lagrangian model to investigate the flow field of the kerosene-fueled rotating detonation with hydrogen addition. We explore the interaction between the rotating detonation flow field and the cooling air induced by multiple columns of uniformly distributed film cooling holes and also analyze the cooling effectiveness of film cooling. In the flow field where the rotating detonation wave passes through the film hole periodically at a high frequency, an increase in the number of film hole columns can decrease the fluctuation amplitude of the cooling air mass flow rate, and the recovery time of the blockage of film cooling holes shortens within a complete rotating detonation cycle. At a low injection pressure of 0.4 MPa, the cooling jet can barely be injected into the combustor. As the injection pressure increases to 0.6 and 0.8 MPa, the mass flow rate of cooling air increases significantly with enhanced cooling efficiency; however, a further rise to 1.0 MPa may result in the detachment of cooling air from the surface, without providing additional improvements in the protection area and cooling efficiency. Along the axial direction of the RDE, film cooling holes demonstrate an enhancement in cooling efficiency, which is found to maximize near the outlet.
