Download or read book Detonation Control for Propulsion written by Jiun-Ming Li and published by Springer. This book was released on 2017-12-05 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the latest developments in detonation engines for aerospace propulsion, with a focus on the rotating detonation engine (RDE). State-of-the-art research contributions are collected from international leading researchers devoted to the pursuit of controllable detonations for practical detonation propulsion. A system-level design of novel detonation engines, performance analysis, and advanced experimental and numerical methods are covered. In addition, the world’s first successful sled demonstration of a rocket rotating detonation engine system and innovations in the development of a kilohertz pulse detonation engine (PDE) system are reported. Readers will obtain, in a straightforward manner, an understanding of the RDE & PDE design, operation and testing approaches, and further specific integration schemes for diverse applications such as rockets for space propulsion and turbojet/ramjet engines for air-breathing propulsion. Detonation Control for Propulsion: Pulse Detonation and Rotating Detonation Engines provides, with its comprehensive coverage from fundamental detonation science to practical research engineering techniques, a wealth of information for scientists in the field of combustion and propulsion. The volume can also serve as a reference text for faculty and graduate students and interested in shock waves, combustion and propulsion.

This book was released on 2022-12-16 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the theories and research progress in gaseous detonation research, and proposes a universal framework theory that overcomes the current research limitations. Gaseous detonation is an extremely fast type of combustion that propagates at supersonic speed in premixed combustible gas. Being self-sustaining and self-organizing with the unique nature of pressure gaining, gaseous detonation and its gas dynamics has been an interdisciplinary frontier for decades. The research of detonation enjoyed its early success from the development of the CJ theory and ZND modeling, but phenomenon is far from being understood quantitatively, and the development of theories to predict the three-dimensional cellular structure remains a formidable task, being essentially a problem in high-speed compressible reacting flow. This theory proposed by the authors’ research group breaks down the limitation of the one-dimensional steady flow hypothesis of the early theories, successfully correlating the propagation and initiation processes of gaseous detonation, and realizing the unified expression of the three-dimensional structure of cell detonation. The book and the proposed open framework is of high value for researchers in conventional applications such as coal mine explosions and chemical plant accidents, and state-of-the-art research fields such as supernova explosion, new aerospace propulsion engines, and detonation-driven hypersonic testing facilities. It is also a driving force for future research of detonation.

Available in PDF, EPUB and Kindle. Book excerpt: This numerical study explored the mechanisms responsible for the re-initiation of a detonation, which quenched while diffracting over a half-cylinder obstacle. Its purpose was to accurately predict when detonation re-initiations occur, determine roles of re-initiation mechanisms, and compare effects of chemical models. The model used reactive Euler equations with the one-step Arrhenius or two-step chain-branching chemical models, calibrated to post-shock conditions to reproduce the ignition delay. Simulations were validated using the stoichiometric methane-oxygen experiments of Bhattacharjee et al.. The model accurately predicted detonation re-initiation conditions found in experiments with good qualitative and quantitative agreement. While the one-step model was sufficient in predicting re-initiation, the two-step model reproduced finer details. Kelvin-Helmholtz and Richtmyer-Meshkov instabilities did not appear to influence detonation re-initiation of the Mach stem. Detonation re-initiation occurred due to adiabatic compression of the Mach stem, or transport of a flame along the wall jet. Transverse detonations were poorly reproduced.

Book excerpt: Nesta dissertação apresentam-se os resultados de um estudo numérico da interação entre uma onda de detonação oblíqua forte estabilizada pela rampa de um diedro e o leque expansão gerado pela deflexão da superfície do diedro. Neste estudo foi utilizado um código numérico que resolve asequações que governam o escoamento de uma mistura reativa de hidrogênio e ar. Estas equações são discretizadas por um procedimento do tipo volumes finitos centrado na célula de cálculo, segundo um esquema que leva em contaas velocidades características do escoamento. A presença de ondas de choque e detonação requer o uso de procedimentos de adaptação de malha. Neste trabalho procedimentos de enriquecimento e empobrecimento de malha são usados, o primeiro para melhorar a resolução das regiões do escoamento nas quais ocorrem grandes gradientes das propriedades, enquanto o segundo para retirar pontos da malha em locais onde os gradientes são pequenos. Mostra-se que este procedimento de empobrecimento, desenvolvido neste trabalho, resulta em ganhos no tempo de processamento. Na determinação dos parâmetros que levem a obter ondas do tipo Chapman-Jouguet como resultado da interação, inicialmente é realizada uma análisequase uni-dimensional baseada nos diagramas das polares de detonação e nos diagramas do tempo de indução da mistura reativa. Em seguida, os resultados das simulações numéricas mostram que a obtenção de uma detonação do tipo Chapman-Jouguet é possível para valores intermediáriosdo ângulo diedro, dentro da faixa das detonações estáveis. Quando o ângulo do diedro é próximo ao ângulo máximo permitido para detonações estáveis obteve-se o desacoplamento da onda de detonação, com a subsequente extinção do processo de combustão.
