Review on the Rotating Detonation Engine and It’s Typical Problems

Abstract

Detonation is a promising combustion mode to improve engine performance, increase combustion efficiency, reduce emissions, and enhance thermal cycle efficiency. Over the last decade, significant progress has been made towards the applications of detonation mode in engines, such as standing detonation engine (SDE), Pulse detonation engine (PDE) and rotating detonation engine (RDE), and the understanding of the fundamental chemistry and physics processes in detonation engines via experimental and numerical studies. This article is to provide a comprehensive overview of the progress in the knowledge of rotating detonation engine from the different countries. New observations of injection, ignition, and geometry of combustor, pressure feedback, and combustion modes of RDE have been reported. These findings and advances have provided new opportunities in the development of rotating detonation for practical applications. Finally, we point out the current gaps in knowledge to indicate which areas future research should be directed at.

Identification of Multiscale Vortex Structures and Transition Fluid Features in CFD and Numerical Astrophysics

“…Over the past decade, significant progress has been made in the field of simulation a deflagration combustion mode of gases in rotating detonation engines (RDE). Combustion under pressure in high-speed ramjet and rocket engines has become the subject of interest in a large number of experimental and numerical studies, in particular in the serial studies noted in [15,16]. The mathematical model describing the processes in the combustion chamber include balance equations for a multicomponent mixture of fuel and oxidizing agent, with chemical transformations and turbulent transfer of mass, momentum, and energy.…”

Applications of the continuously rotating detonation to combustion engines at the Łukasiewicz - Institute of Aviation

“…Detonative combustion could be applied in three different configurations of engines: Standing Detonation Engines, Pulsed Detonation Engines (PDE) and Rotating Detonation Engines (RDE). Application of detonation combustion for Standing Detonation Engines was already proposed in fifties of the last century [5,25,26], but beside theoretical analyses they have been extensively tested, since for a such engine operation speed is limited to the velocity close to the theoretical detonation velocity. Such engine could only operate in flight velocity higher than theoretical detonation velocity, but not too much higher, since then external drag of the engine could overcome thrust produced by the engine.…”

“…[34], but also con-shaped and successfully tested by Kawalec et al [33]. There are also other geometries already tested, such as cylindrical chamber with short insert and hollow chamber and disk-shaped connected to the nozzle and other [24][25][26][27][35][36][37][38][39][40][41].…”

Visualization and Performance Evaluation of a Liquid-Ethanol Cylindrical Rotating Detonation Combustor

“…7) RDCs have been demonstrated in space, 8) and research and development for practical use of RDCs are currently being conducted. [9][10][11] In this way, RDCs are being actively researched by research institutes all over the world. Nonetheless, annular RDCs continue to suffer from drawbacks such as countermeasures against heat load on the inner cylinder and structural weight increase.…”
