Available in PDF, EPUB and Kindle. Book excerpt: A numerical investigation has been made for supersonic flow past a cylindrical aft body with and without base bleed and a cylindrical boat tail. Comparison was made to available experimental data. The effect of grid cell density and turbulence models were examined. The calculation of the base flow region was much more highly dependent on grid density that was the forebody or outer flow field Agreement between the numerical and experimental results improved with the inclusion of the base bleed.

This book was released on 1967 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of an experimental investigation of unsteady supersonic flow past cylinders are presented. The purpose of the experiment was to determine the basic criteria characterizing an unsteady flow behind a two-dimensional shock wave having constant time parameters and to ascertain the correlation between the variable location of a reflected shock wave and the surface pressure on the body. The experiments were carried out by subjecting cylinders with flat and spherical bluntness to axisymmetrical and transverse flows in a shock tube. The range of the Mach numbers of the incident shock-waves was from 1.5 to 6. The magnitudes of maximum shock detachment distance at the stagnation point obtained were compared with available data and were found to be in good agreement. (Author).

This book was released on 2001-09 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computational fluid dynamics (CFD) approach to predicting high- speed aerodynamic flow fields of interest to the U.S. Army Research Laboratory (ARL) has been carried out The aerodynamic problems of particular interest are: (1) supersonic flow past the aftbody of projectiles with base mass injection, (2) supersonic flow past the M549 projectile, and (3) subsonic, transonic, and supersonic flow past an M864 projectile with base bleed and wake combustion. The commercially available FLUENT (Fluent, Inc. FLUENT. Version 5.1.1, Lebanon, NH, 1999.) CFD code was utilized. The computational effort supports an ongoing ARL- sponsored experimental investigation. Of particular interest in the present investigation is the careful characterization of the various turbulence models employed in the CFD code. Additionally, the ease of use and set-up as well as the computational time will be described. An experimental effort (Dutton, J. C., and A. L. Addy. 'Fluid Dynamic Mechanisms and Interactions Within Separated Flows'. U.S. Army Research Office Research Grant DAAH04-93-G-0226 and the Department of Mechanical and Industrial Engineering, University of illinois, Urbana-Champagne, Urbana, IL, August 1998.) consisting of detailed laser Doppler velocimeter (LDV), particle image velocimeter (PIV), and high-speed wall pressure measurements has been made in axisymmetric and planar subsonic and supersonic flows with embedded separated regions. The present work seeks to predict similar flow fields computationally and to address areas of agreement and disagreement.

Download or read book Investigation of Supersonic Flow Over an Axisymmetric Protuberance written by Josiah Ross and published by . This book was released on 2014 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: The behavior of a supersonic fluid flow field over an axisymmetric cylindrical body has been simulated using ANSYS Fluent computational fluid dynamics software. The simulated body was altered for successive simulations to incorporate a protuberance interrupting the one dimensional flow along the surface. The effect of introducing this protuberance was investigated for Mach numbers ranging from 1.5 to 5.5 in increments of 0.5. To account for flow characteristics not associated with an infinite wall simulation, the body was modeled as a 2.5 caliber Tangent Ogive nose cone profile leading a cylindrical wall in free stream conditions. Once the initial shock is formed, the flow downstream is investigated for the behavior it exhibits in the presence of a surface protuberance. The surface protuberance will cause the flow to wrap around the curvature of the surface. This abrupt change in direction and redirection results in a separation in the flow structure from the wall, which creates a region known as a recirculation zone. Flow becomes discontinuous due to the turning angle of the surface and therefore detaches and must resume parallel flow farther past the protuberance. Flow reattachment downstream of such an obstacle is determined in this research in order to develop a relationship between flow speed, protuberance geometry and recirculation region length. Pressure distributions along the surface beyond the separation point caused by the protuberance angle were used to find the reattachment length. Each pressure distribution contained a point where the rate of change leveled off from the initial chaotic region following the protuberance apex. These points were considered the beginning of the reattachment region and thus the end of the separation region. Correlations for such behavior as a function of the protuberance length scale and Mach number are developed and discussed. The dominance of the Mach number influence in the reattachment length of the separation region is apparent in the final data analysis, as well as a negative correlation of increasing protuberance height. It is apparent that an increased Mach number results in a longer reattachment length. However, as the aspect ratio of the protuberance increases, the reattachment length decreases.

Download or read book Experimental Investigations of Instability of Supersonic Flow about Cup-shaped Bodies written by Raymond Edward Rose and published by . This book was released on 1966 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aerodynamic characteristics of spherical-segment cups, ranging from a disc to a hemisphere, and cylindrical cups, having different depths, have been investigated in supersonic flow. The supersonic flow about hemispherical cups and cylindrical cups of a particular depth was found to be very unstable. The instability was characterized by violent oscillations of the detached shock wave coupled with unsymmetrical mass spillage from the cavity. The flow and shock wave instability were studied in a wind tunnel by means of high-speed motion pictures, shadowgraphs, schlieren photographs, wave diagram analysis, and surface pressure measurements. The water analogy was also used to study the flow instability.

Available in PDF, EPUB and Kindle. Book excerpt: The results of an experimental investigation of supersonic flows past bodies of revolution with annular recesses of various lengths by means of a wind tunnel in the Mach ranges M = 1.79 to 3.69 and Re = 290,000 to 1,050,000 for 1 cm are presented. Various cylindrical models 6 to 60 mm in diameter with conical forward sections and with annular recesses of different lengths and depths were considered. The length of the recess 1 sub cr called critical for which the flows changed from flows with one to flows with two stagnation regions and also its ratio to its depth were determined experimentally from schlieren photographs. An attempt was made to establish the relationship between 1 sub cr/h and M and Re. The results of measurements on aerodynamic drag confirmed the conclusions from an analysis of the available data stating that the transition from the first to the second type of flow is accompanied by a jump-type increase in drag, thus an increase in the diameter of the rear cylinder in the region 1 sub cr may lead to a decrease in drag, and vice versa. The transition from the first type of flow to the second occurs in a quite narrow range of the value K1 sub cr/L = 12 to 22, where k is the coefficient accounting for the curvature of the model.

This book was released on 2013-06-29 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the appearance of computers, numerical methods for discontinuous solutions of quasi-linear hyperbolic systems of partial differential equations have been among the most important research subjects in numerical analysis. The authors have developed a new difference method (named the singularity-separating method) for quasi-linear hyperbolic systems of partial differential equations. Its most important feature is that it possesses a high accuracy even for problems with singularities such as schocks, contact discontinuities, rarefaction waves and detonations. Besides the thorough description of the method itself, its mathematical foundation (stability-convergence theory of difference schemes for initial-boundary-value hyperbolic problems) and its application to supersonic flow around bodies are discussed. Further, the method of lines and its application to blunt body problems and conical flow problems are described in detail. This book should soon be an important working basis for both graduate students and researchers in the field of partial differential equations as well as in mathematical physics.
