This book was released on 1965 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation of mixing and burning is described in which the progress of mixing and burning is followed by observing the spatial variation of static pressure in the mixing duct. Experiments showed that the duct length required for mixing and for mixing with simultaneous chemical reaction of the gaseous fuel jet are identical and are independent of the amount to be mixed and burned. In order to aid in the interpretation of the experimental data, the flow field is assumed to be ''piecewise uniform'' over the mixing duct cross section. The analytical variation of the static pressure in the mixing agrees in a semi-quantitative manner with the experimental data. The experimental and analytical results are combined to provide the spatial and temporal variation of the mixing paramete. It is found that the combustion process has the general effect of increasing the mean duct velocity which increases the turbulent exchange coefficient and, hence, increases the mixing rate. For the experimental geometry considered, the mixing and burning time is roughly half of the time required for mixing only and is independent of the energy released in the chemical reaction.

Download or read book Scramjets written by Mostafa Barzegar Gerdroodbary and published by Butterworth-Heinemann. This book was released on 2020-07-21 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scramjet engines are a type of jet engine and rely on the combustion of fuel and an oxidizer to produce thrust. While scramjets are conceptually simple, actual implementation is limited by extreme technical challenges. Hypersonic flight within the atmosphere generates immense drag, and temperatures found on the aircraft and within the engine can be much greater than that of the surrounding air. Maintaining combustion in the supersonic flow presents additional challenges, as the fuel must be injected, mixed, ignited, and burned within milliseconds. Fuel mixing, along with the configuration and positioning of the injectors and the boundary conditions, play a key role in combustion efficiency. Scramjets: Fuel Mixing and Injection Systems discusses how fuel mixing efficiency and the advantage of injection systems can enhance the performance of the scramjets. The book begins with the introduction of the supersonic combustion chamber and explains the main parameters on the mixing rate. The configuration of scramjets is then introduced with special emphasis on the main effective parameters on the mixing of fuel inside the scramjets. In addition, basic concepts and principles on the mixing rate and fuel distribution within scramjets are presented. Main effective parameters such as range of fuel concentration for the efficient combustion, pressure of fuel jet and various arrangement of jet injections are also explained. This book is for aeronautical and mechanical engineers as well as those working in supersonic combustion who need to know the effects of compressibility on combustion, of shocks on mixing and on chemical reactions, and vorticity on the flame anchoring. Explains the main applicable approaches for enhancement of supersonic combustion engines and the new techniques of fuel injection Shows how the interaction of main air stream with fuel injections can develop the mixing inside the scramjets Presents results of numerical simulations and how they can be used for the development of the combustion engines
Download or read book Jet in Supersonic Crossflow written by Mingbo Sun and published by Springer. This book was released on 2019-02-18 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on research into jets in supersonic crossflow carried out by the authors’ team over the past 15 years, this book summarizes and presents many cutting-edge findings and analyses on this subject. It tackles the complicated mixing process of gas jets and atomization process of liquid jets in supersonic crossflow, and studies their physical mechanisms. Advanced experimental and numerical techniques are applied to further readers’ understanding of atomization, mixing, and combustion of fuel jets in supersonic crossflow, which can promote superior fuel injection design in scramjet engines. The book offers a valuable reference guide for all researchers and engineers working on the design of scramjet engines, and will also benefit graduate students majoring in aeronautical and aerospace engineering.

Download or read book Investigation of the Mixing of Coaxial Heterogeneous Gas Jets as Applied to Supersonic Combustion written by Gilles L. Hamelin and published by . This book was released on 1965 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation of the turbulent mixing of a sonic jet of helium discharging coaxially into a supersonic jet of air was made using a two dimensional mixing chamber. Volumetric concentration profiles were obtained and mass concentration and velocity along the jet centerline were plotted. The results indicated that both these vary inversely with the distance from the mixing origin raised to a four third power. Schlieren photography was applied in a semi-quantitative manner to confirm the validity of the above findings. This research project finds a potential application in the study and analysis of supersonic combustion ramjet engines. (Author).
