This book was released on 1966 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The method of characteristics (extended from two to three independent variables) is used to solve the problem of supersonic flow of an ideal gas over a blunt body. The steady motion of the gas is described by a system of partial differential equations. A Cartesian coordinate system is fixed to the flow. A scheme based on the relations on the characteristic planes is proposed for calculating the supersonic portion of the flow, and therefore the calculation of a point depends on whether it is found in the shock wave, in the flow field, or on the surface of the body. The computational procedures for these three cases are outlined and illustrated by examples. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The method of characteristics is formulated for the computation of the supersonic flow of an inviscid, reacting gas over a smooth three-dimensional body. Various methods of constructing networks of bicharacteristic lines are examined from the point of view of numerical stability and accuracy. A new method of forming the network, which consists of projecting forward along streamlines from data points on specified data planes, is found to be most easily adopted to the particular requirements of nonequilibrium chemistry. The general method was coded for the IBM 7090 computer and the program demonstrated for the case of an ideal gas. Calculations were made for the case of an ideal gas. Calculations were made for the flow about a spherical-tip 15 degree half-angle cone at 10 degree angle of attack and a generalized elliptical body at zero incidence. Since the program yields the pressure distribution along specified streamlines, it is straightforward, in principle, to link it to a finite-rate chemistry stream tube program to treat three-dimensional, nonequilibrium flows.

This book was released on 1968 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: To solve the problem of a three-dimensional supersonic gas flow around three-dimensional bodies several effective computation schemes have been developed in recent years, which are based on the use of the finite difference method, the method of characteristics and the semi-characteristics method. Such numerical methods make it possible to determine with the required accuracy both the overall aerodynamic characteristics and the distribution of the various parameters on the surface of the body and across the shock layer. In these numerical computations it is also not difficult to account for physical-chemical processes occuring in the gas at high temperatures. (Author).
Download or read book A Method of Characteristics Computer Program for Three dimensional Supersonic Internal Flows written by W. C. Armstrong and published by . This book was released on 1979 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reference-plane method of characteristics is applied to the computation of the supersonic flow in a three-dimensional (3-D) channel such as a propulsion nozzle. The fluid is assumed to be an inviscid ideal gas and the flow is assumed to be shock-free, although it can be rotational. Both the basic equations and the numerical procedures are described, as is the computer program, which was written in FORTRAN IV language for the IBM 370/165 computer. The validity of the computer program was established by computing, in various ways, an axisymmetric nozzle flow as a three-dimensional flow; the numerical results are in good agreement with the results from a well-established computer program for axisymmetric flow.

This book was released on 1977 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive computational procedure is presented for predicting the supersonic region of the flow field on advanced reentry vehicle shapes in steady flight at pitch and yaw. The procedure utilizes explicit second order accurate finite difference methods applied to the conservation law form of the steady inviscid flow equations. Improved numerical methods are used at the body surface and the bow shock wave. Provisions for treating body geometries with discontinuous slopes are also included. Either perfect gas or real gas equilibrium thermodynamic properties can be used. The computational procedure is implemented as a fortran computer code which provides a practicable representation of the inviscid flow field and the resulting aerodynamic force and moment on the vehicle. This volume contains detailed instructions for operating the code and interpreting the output results.

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.
