Book Description
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.

Book Description
The objective of this work was to develop a parallel algorithm that would be used in the simulation of the detonation process in the chamber of a pulse detonation engine. The emphasis is laid on reducing computation time while maintaining the accuracy of the solution and subsequently developing a numerical solution to be in agreement with real-world physical characteristics of a detonation wave initiation, build-up and progression. The flow is assumed to be unsteady, inviscid and non heat conducting. To adhere to real time effects, the flow equations are coupled with finite rate chemistry and the vibrational energy equation are based on a two-temperature model, to account for possible vibrational non-equilibrium. Finite Volume formulation is employed to ensure conservation and to allow proper handling of discontinuities. Runge-Kutta integration scheme has been utilized to obtain a time-accurate solution, with Roes flux difference splitting scheme applied to cell face fluxes. For higher-order spatial accuracy, MUSCL technique is employed. Equation stiffness has been taken care of by observing point implicit treatment of the source terms and detonation is initiated with the application of a localized hot-spot. The parallel algorithm has been developed using Message Passing Interface standard developed by the Argonne National Laboratory for the purposes of solving equations in a distributed environment. A proto-cluster of Beowulf type consisting of 8-nodes has been assembled and made operational, and an algorithm which performs space-time calculations simultaneously on the nodes has been successfully developed. A two-step global model for Hydrogen-Air mixture has been selected for validating the parallel algorithm with existing results, to establish veracity and accuracy while reducing computation time to almost a fourth. Excellent agreement has been found on comparison of the results with the same code when solved in a single processor.

Book Description
In order to study multi-dimensional unstable detonation waves, a high order numerical scheme suitable for calculating the detailed transverse wave structures of multidimensional detonation waves was developed. The numerical algorithm uses a multi-domain approach so different numerical techniques can be applied for different components of detonation waves. The detonation waves are assumed to undergo an irreversible, unimolecular reaction A yields B. Several cases of unstable two dimensional detonation waves are simulated and detailed transverse wave interactions are documented. The numerical results show the importance of resolving the detonation front without excessive numerical viscosity in order to obtain the correct cellular patterns.
