Book A Time dependent Method for Calculating Supersonic Angle of attack Flow about Axisymmetric Blunt Bodies with Sharp Shoulders and Smooth Nonaxisymmetric Blunt Bodies

Download or read book A Time dependent Method for Calculating Supersonic Angle of attack Flow about Axisymmetric Blunt Bodies with Sharp Shoulders and Smooth Nonaxisymmetric Blunt Bodies written by Richard W. Barnwell and published by . This book was released on 1971 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: A time-dependent numerical method for calculating supersonic flow about blunt bodies at large angles of attack is presented. The axisymmetric bodies with sharp shoulders which are treated are constructed with a generator composed of segments of constant curvature. The nonaxisymmetric bodies have continuous slope and curvature. All flow fields are inviscid and adiabatic and have one plane of symmetry. A modification to the method of characteristics is introduced for use at the shock wave. A two-step finite-difference method of second-order accuracy is used at the body surface and in the region between the shock and body. A new finite-difference technique is introduced for use at sharp sonic shoulders. Comparisons of the results of the present method with experiment and the results of other methods are made for the flow of equilibrium air past the Apollo command module at the trim angle of attack and for perfect gas flow past a spherical cap and a spherically blunted cone at angle of attack. Both the cap and the blunted cone are terminated with sharp shoulders. Results are presented also for perfect gas flow past a prolate spheroid with its major axis normal to the flow.

Book Supersonic Flow Around Cones at Large Yaw

Download or read book Supersonic Flow Around Cones at Large Yaw written by G. B. W. YOUNG and published by . This book was released on 1951 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Equations were developed for the flow properties in the region bounded by a supersonic cone body at large angle of attack and its attached shock wave, for use with the tabulations of Kopal. A comparison of the theoretical results is made with the experimental data of Cronvich. A slight discrepancy which increases with increasing Mach number was found in the value of K sub DYH, the yawing head drag as tabulated by Kopal. (Author).

Book Supersonic Flow Past Conical Bodies with Nearly Circular Cross Sections

Download or read book Supersonic Flow Past Conical Bodies with Nearly Circular Cross Sections written by Martin C. Jischke and published by . This book was released on 1978 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inviscid, supersonic conical flows past bodies whose cross-section deviates slightly from that of a right circular cone are studied by means of a perturbation technique. The effects of small angles of attack and yaw are included. Using the hypersonic small disturbances theory approximations, we have developed explicity results for the flow field velocity components, pressure, entropy, and shock shape for cases n, m = 1, 2, 3, 4. Comparisons of theory with experiment for n = 1, 2 are favorable. The streamsurfaces of the velocity field are calculated and possible waverider geometries that can be developed therefrom are discussed.

Book A Numerical Method for Calculating Steady Unsymmetrical Supersonic Flow Past Cones

Download or read book A Numerical Method for Calculating Steady Unsymmetrical Supersonic Flow Past Cones written by Daniel Ejike Ndefo and published by . This book was released on 1969 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Telenin's numerical method is adapted to the problem of steady supersonic flow past pointed conical bodies at yaw. The method is formulated for cones of circular cross-sections with the intention of determining bounded analytic solutions uniformly valid in the region between the shock and cone surfaces. Attention is focused on the nature of the entropy field and the behavior of the streamlines as influenced by variations in the free-stream conditions. As an example, numerical computations are carried out for flow past a circular cone of semi-apex angle 20 deg yawed at angles of attack varying from 0 to 20 deg with respect to a free-stream of Mach number 3.53. Solutions are compared with experimental results and with solutions based on other numerical methods. The solutions confirm the existence of a vortical singularity at the leeward generator of the cone, but no evidence is found of the 'lift-off' of this singularity as suggested by Ferri. The entropy layer is shown to be very thin at small angles of attack but relatively thick at large angles of attack. The directions from which the streamlines enter the vortical singularity are found to depend on the angle of attack. (Author).

Book Difference Methods for Initial Boundary Value Problems and Flow Around Bodies

Download or read book Difference Methods for Initial Boundary Value Problems and Flow Around Bodies written by You-lan Zhu and published by Springer Science & Business Media. 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.
