This book was released on 1971 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation is directed primarily at the second order solution of the three dimensional, supersonic flow field around an arbitrarily-shaped body which, although otherwise of smooth contour, has a protuberance that generates a shock wave and substantially disturbs the flow downstream. Such configurations occur for example, in fuselage-canopy combinations. The calculation of the flow field about a body with no local protuberance is considered first, the solution being based on the so-called method of near-characteristics. Typical numerical results are presented for circular and elliptic cones, tangent ogives of circular and elliptic cross section, and a representative non-axisymmetric compression surface. Comparisons with results from conical flow theories and with experimental data are made wherever possible. The theoretical analysis and computational procedure evolved for the primary body is then extended to permit the addition of the shock-producing protuberance. This approach enable the flow upstream of the secondary shock to be considered uniform.

Available in PDF, EPUB and Kindle. Book excerpt: Some 100 numerical computations have been carried out for unyawed bodies of revolution with detached bow waves. The gas is assumed perfect with y=5/3, 7/5, or 1. Free-stream Mach numbers are taken as 1.2, 1.5, 2, 3, 4, 6, 10, and [infinity symbol]. The results are summarized with emphasis on the sphere and paraboloid.

This book was released on 2018-07-13 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction between a shock wave (attached to a wedge) and small amplitude, three-dimensional disturbances of a uniform, supersonic, freestream flow are investigated. The paper extends the two-dimensional study of Duck et al, through the use of vector potentials, which render the problem tractable by the same techniques as in the two-dimensional case, in particular by expansion of the solution by means of a Fourier-Bessel series, in appropriately chosen coordinates. Results are presented for specific classes of freestream disturbances, and the study shows conclusively that the shock is stable to all classes of disturbances (i.e. time periodic perturbations to the shock do not grow downstream), provided the flow downstream of the shock is supersonic (loosely corresponding to the weak shock solution). This is shown from our numerical results and also by asymptotic analysis of the Fourier-Bessel series, valid far downstream of the shock. Duck, Peter W. and Lasseigne, D. Glenn and Hussaini, M. Y.
