Book Synopsis Transverse Jet Penetration in Supersonic Flows with Variable Boundary Layer Thickness by : Ron Portz
Download or read book Transverse Jet Penetration in Supersonic Flows with Variable Boundary Layer Thickness written by Ron Portz and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Penetration was found to increase strongly with boundary layer thickness at low Mach numbers but as Mach number increases, boundary layer thickness has less effect. A new formula is proposed to predict penetration based on a set of independent variables. This formula is compared to new test data and previous results and achieves good correlation for all studies.
Book Synopsis Jet in Supersonic Crossflow by : Mingbo Sun
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.
Book Synopsis Turbulent Shear Layers in Supersonic Flow by : Alexander J. Smits
Download or read book Turbulent Shear Layers in Supersonic Flow written by Alexander J. Smits and published by Springer Science & Business Media. This book was released on 2006-05-11 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: A good understanding of turbulent compressible flows is essential to the design and operation of high-speed vehicles. Such flows occur, for example, in the external flow over the surfaces of supersonic aircraft, and in the internal flow through the engines. Our ability to predict the aerodynamic lift, drag, propulsion and maneuverability of high-speed vehicles is crucially dependent on our knowledge of turbulent shear layers, and our understanding of their behavior in the presence of shock waves and regions of changing pressure. Turbulent Shear Layers in Supersonic Flow provides a comprehensive introduction to the field, and helps provide a basis for future work in this area. Wherever possible we use the available experimental work, and the results from numerical simulations to illustrate and develop a physical understanding of turbulent compressible flows.
Book Synopsis Side View and End View Mixing Measurements of a Sonic Transverse Jet in a Supersonic Crossflow by : Adam R. Pizzaia
Download or read book Side View and End View Mixing Measurements of a Sonic Transverse Jet in a Supersonic Crossflow written by Adam R. Pizzaia and published by . 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.

Book Synopsis A Study of Penetration of a Liquid Injectant Into a Supersonic Flow by : Kenneth P. Horn
Download or read book A Study of Penetration of a Liquid Injectant Into a Supersonic Flow written by Kenneth P. Horn and published by . This book was released on 1967 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper reports a study of normal and lateral spray penetration for small diameter, high pressure, liquid jets issuing at an angle to a uniform supersonic stream. The experimental program described was carried out in a 4-in. by 4-in. blow down supersonic wind tunnel. The flow field is observed by means of a schlieren system, and the spray distribution is indicated by the light scattered by the liquid droplets. The data on normal penetration, in good agreement with data inferred from other investigations, indicate that a single-parameter correlation exists between the properly nondimensionalized penetration height and the injection pressure ratio. Injecting the coolant at a forward angle to the flow produces no substantial change in the penetration height. The data on lateral penetration show the spray width behind the jet to be proportional to the jet diameter with only a weak dependence on the injection pressure ratio. Analytical models proposed by previous investigators are critically examined in light of the results. No single model leads to a proper scaling law for both normal and lateral penetration. (Author).

Book Synopsis Analysis of the Three-dimensional Compressible Turbulent Boundary Layer on a Sharp Cone at Incidence in Supersonic and Hypersonic Flow by : John C. Adams
Download or read book Analysis of the Three-dimensional Compressible Turbulent Boundary Layer on a Sharp Cone at Incidence in Supersonic and Hypersonic Flow written by John C. Adams and published by . This book was released on 1972 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical approach toward numerical calculation of the three-dimensional turbulent boundary layer on a sharp cone at incidence under supersonic and hypersonic flow conditions is presented. The theoretical model is based on implicit finite-difference integration of the governing three-dimensional turbulent boundary-layer equations in conjunction with a three-dimensional scalar eddy-viscosity model of turbulence. Comparison is made of present theory with detailed experimental measurements of the three-dimensional turbulent boundary-layer structure (velocity and temperature profiles), the surface streamline direction (obtained via an oil-flow technique) and surface heat-transfer rate.

Book Synopsis On the Near Field Mean Flow Structure of Transverse Jets Issuing Into a Supersonic Freestream by : Dean Anthony Dickmann
Download or read book On the Near Field Mean Flow Structure of Transverse Jets Issuing Into a Supersonic Freestream written by Dean Anthony Dickmann and published by ProQuest. 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.
