This book was released on 1969 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new method of characteristics numerical scheme for three-dimensional steady flow has been developed which has second-order accuracy. A complete numerical algorithm for computing internal supersonic flows of the type encountered in ramjet, scramjet or rocket propulsion systems has been developed and programmed for both the IBM 7094 and CDC 6500 computers. The method has been tested for order of accuracy using the exact solution for source flow and Prandtl-Meyer flow. The results of these tests have verified the second-order accuracy of the scheme. Additional accuracy tests using existing methods for solution of two-dimensional axisymmetric flows have shown that the scheme produces accuracies comparable to that of the two-dimensional method of characteristics. The computer program has been used to generate the flow field for several three-dimensional nozzle contours and for nonsymmetric flow into an axisymmetric nozzle. These results reveal the complex natureof three-dimensional flows and the general inadequacy of quasi-three-dimensional analyses which neglect crossflow. An operationally convenient computer program was produced. The program has the capability to analyze nonisoenergetic and nonhomentropic flows of a calorically perfect gas or homentropic flows of a real gas in chemical equilibrium. The initial-value surface options include uniform flow, source flow or axisymmetric tabular data. The nozzle boundary options include conical nozzles, axisymmetric contoured nozzles and super-elliptical nozzles.

Book excerpt: A new method of characteristics numerical scheme for three- dimensional steady flow was developed which has second-order accuracy. Heretofore all such schemes for three-dimensional flow have had accuracies less than second-order.

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.
