This book was released on 2014 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary investigation was to determine if mixing of a sonic transverse jet in the side-view plane was correlated to or equal to the mixing in the end-view plane. The analysis was conducted by imaging a sonic jet in a supersonic crossflow at jet momentum ratios of 1.2, 2.7, and 5.2. Because of the difficulty of placing a camera streamwise to a supersonic crossflow to obtain end view images, off axis imaging was carried out. Overall, the jets appear to be more symmetric when injected into the thin boundary layer than in the thick boundary layer. Centerline probability density functions in the end view plane were compared with probability density functions in the side view plane. The probability of finding unmixed fluid at the windward side of the jet was higher than finding unmixed fluid toward the center or near the orifice plane. Different paths other than those that fall on the mid planes were analyzed and compared in the end-view plane. The effect of the boundary layer thickness on the penetration and mixing of the sonic jet in supersonic flow was investigated.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The near field mean flow structure of transverse jets issuing from a surface into supersonic crossflow is examined using numerical methods and separation topology. The Navier-Stokes solver Falcon, developed at Lockheed Martin, was used to simulate the interaction between the jet and freestream over a flat plate and a generic missile body. The near field flow structure included a lambda bow shock upstream of the jet interacting with the approaching boundary layer that forms a pair of horseshoe vortices while another lambda-structure closer to the jet formed a second pair of horseshoe vortices. As the jet was turned downstream by the crossflow, the so-called barrel shock terminates in a Mach disk while vortices formed within the jet plume. Downstream of the jet exit, new flow structure was identified in the form of three pairs of vortices. Horn, near field and far field wake vortices were present downstream of the jet as well as a series of compression waves resulting in a gradual pressure rise downstream of the jet overexpansion. The wave formations and the vortices formed from them affected separation topology, performance parameters and amplification coefficients. The current understanding of the flow structure in the near field of a transverse jet in supersonic flow must be amended to include these newly identified vortices and compression waves.

This book was released on 2014-02 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-fluid dynamics' simulations require numerical treatments based on the flow characteristics, including flow speed, turbulence, thermodynamic state, and time/length scales. Two distinct problems are investigated: supersonic jet and crossflow interactions; and liquid plug propagation and rupture in lung airways. Supersonic crossflow is the mechanism for fuel injection in SCRAMJET engines. The regime is highly unsteady, involving shocks, turbulent mixing, and large-scale vortical structures. An eddy-viscosity-based multi-scale turbulence model is proposed to resolve turbulent structures consistent with grid resolution and turbulence length scales. Additionally, an adaptive turbulent mixing approach is also proposed. Predictions from the new models show great improvement over the standard RANS models. For liquid plug rupture, simulations are conducted using an Eulerian-Lagrangian approach with a continuous-interface method. A new reconstruction scheme is developed to capture plug rupture by altering the connectivity information of the interface mesh.During the plug rupture process, a sudden increase of mechanical stresses on the tube wall is recorded, which can cause tissue damage

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

This book was released on 1995 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: The large scale structure and mixing characteristics of the flowfield surrounding a single, underexpanded, sonic, transverse jet injected into a Mach 1.6 crossflow were experimentally studied. The flowfield was investigated at three distinct sets of flow conditions corresponding to a jet-to-crossflow momentum flux ratio of 1.2, 1.7, and 2.2. Planar laser-induced fluorescence from acetone molecules and planar Mie scattering from condensed ethanol droplets were used to obtain spatially and temporally resolved flowfield visualizations in various side, end, and top view image planes. Statistical processing of the image ensembles produced mean and standard deviation images, two-dimensional spatial autocovariance fields representing the characteristics of the dominant turbulent structures, and probability density functions representing the instantaneous state of scalar mixing in the flowfield. Time-averaged descriptions of the mixing characteristics of this transverse jet flowfield were shown to be inaccurate. Intermittent large scale structures of various sizes, shapes, and orientations strongly influence the distribution of the jet fluid and the crossflow fluid. Relatively high probabilities of unmixed fluid (whether jet or crossflow) persist in many of the mixing regions between the jet and crossflow. The most significant instantaneous mixing in this flowfield seems to occur in the center of wake region slightly below the jet centerline. A counter-rotating streamwise vortex pair in the jet cross section plays an important role in the scalar mixing processes, as it transports jet fluid down towards the wake and entrains crossflow fluid from below up into the jet. The streamwise vortex pair initially develops in an asymmetric and undulating manner, but gradually becomes more symmetric farther downstream of the Mach disk. A relatively large portion of the total jet fluid bypasses the Mach disk through the upstream edge of the barrel shock, thereby retaining a significant fraction of its momentum. This relatively high momentum jet fluid penetrates deeply into the crossflow, contributes to the formation of the largest turbulent structures, and affects the evolution of the streamwise vortex pair.
