This book was released on 2013 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design and off-design studies of the hypersonic air-breathing engines face many challenges, due to the complexity of their internal flows. The mixing and combustion processes in Supersonic-Combustion Ramjet (scramjet) engines involve complicated aerothermochemical features, such as: the interactions between shock-waves and boundary-layer, the shock induced-combustion and the recirculation zones. In this study, a numerical solver is developed and validated to be an efficient design tool capable of simulating these complicated flow features of the supersonic combustors. For the code validation, several test cases are considered to monitor the code ability to solve for the diffusive and turbulent fluxes, and the chemical source term. In addition, the code is validated by resolving the transverse sonic injection into supersonic air flow in the case of Helium injection from a flat plate, and in the case of Hydrogen injection in a single-strut scramjet engine. The effectiveness of this injection technique in mixing and flame-holding is demonstrated. The results show good agreement with the previous numerical and experimental investigations, and prove the simulator's accuracy.

Book excerpt: Research has been undertaken to achieve an improved understanding of physical phenomena present when a supersonic flow undergoes chemical reaction. A detailed understanding of supersonic reacting flows is necessary to successfully develop advanced propulsion systems now planned for use late in this century and beyond. In order to explore such flows, a study was begun to create appropriate physical models for describing supersonic combustion, and to develop accurate and efficient numerical techniques for solving the governing equations that result from these models. From this work, two computer programs were written to study reacting flows. Both programs were constructed to consider the multicomponent diffusion and convection of important chemical species, the finite rate reaction of these species, and the resulting interaction of the fluid mechanics and the chemistry. The first program employed a finite difference scheme for integrating the governing equations, whereas the second used a hybrid Chebyshev pseudospectral technique for improved accuracy. Drummond, J.

This book was released on 2018-07-16 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of a three year study on vortex enhancement of supersonic mixing are discussed. Recent interests in compressible mixing has spurred research in the field of high speed shear layers. It was established that shear layer growth diminishes with increasing convective Mach number; this Mach number is the relative Mach number of the large scale structures in the shear layer with respect to the Mach numbers on either side of the shear layer. The purpose was to evaluate the effect of swirl on compressible mixing rates. Previously analytical and experimental results seem to indicate that swirling flow may significantly modify the shear layer, in some cases resulting in enhanced mixing. Previous studies of the effect of swirl on compressible mixing were incomplete since the amount of swirl in the flowfield was not quantified. This study was undertaken to conclusively determine the effect of swirl on supersonic mixing, including the quantification of the swirl. Preliminary results indicate that the swirl modestly enhances the mixing rates. Settles, Gary S. Unspecified Center...

This book was released on 2024-01-09 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A free jet defined as a rapid stream driven by pressure issuing from the nozzle exit which exhibits excellent characteristics of flow field along the width to axial distance (X/D). Where X is the axial distance and D is the diameter of the nozzle exit. The extensive understanding of flow and mixing characteristics of supersonic jet has been gaining the importance in recent years owing to its vast application in many areas like rockets, aircraft engines, and nozzle for different application etc. Over few decades the fundamentals understanding of jets and the factors affecting jet spread had been studied extensively using techniques like analytical, experimental and numerical. The effectiveness and efficiency of the jet is determined using parameters like jet spread rate, potential core length and jet decay In addition to the above shear layer also defines the efficiency of free jet. Free jet is pressure driven rapid stream which issuing either from nozzle or orifice into a quiescent ambience without any obstruction, it can also be defined using the shear layer. Shear layer is the boundary layer where the interaction between the jet and atmosphere takes place due to the exchange of momentum. The magnitude of the shear layer not only depends on the shape of exit but also the mach number of the jet]. The value of the shear layer increases with respect to the jet Mach number. Hence understanding the physics of shear layer during the evolution of jet is important. On the other hand, the characteristics of jet are also influenced by the shape of nozzle, exit profile, thickness, velocity profile and orientation of jet. Due to the velocity difference between the entraining flow and ambient boundary layer is formed at jet periphery. This boundary layer is called as shear layer. Usually shear layer is a highly unstable due to the jet spread in downstream direction. Which lead to formation of vortices. Secondly, these vortices enhance the mixing characteristics of free jet. The jet is classified into free jet, confined jet, isothermal and non-isothermal jet. A free jet is a rapid stream which discharges into ambient fluid. If the jet is influenced with reverse flow then it is called confined jet. If the jet is attached to the surface called attached jet. Based on the effect of temperature the jet is categorized as isothermal and non-isothermal.
