This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the though that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemi nation. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 37 (thesis year 1992) a total of 12,549 thesis titles from 25 Canadian and 153 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 37 reports theses submitted in 1992, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.
Book Synopsis Comparison of Transonic Flow Solutions in C-D Nozzles by : Robert J Mary (Jr)
Download or read book Comparison of Transonic Flow Solutions in C-D Nozzles written by Robert J Mary (Jr) and published by . This book was released on 1974 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The method of characteristics has proven to be a highly accurate and relatively straight forward technique for computing the supersonic flow field in a two-dimensional or axisymmetric nozzle. However, the method of characteristics requires an initial value line traversing the flow in the fully supersonic region on which the flow properties are known. A parametric study of the effect of different transonic flow calculation methods for establishing the initial value line for axisymmetric converging-diverging nozzles was conducted. The Mach number and radial velocity distributions along a reference start line were calculated and compared for several different transonic solutions for a series of nozzles with different throat radii of curvature. These initial value lines were then used to initiate a method of characteristics analysis of several geometrically different axisymmetric nozzles in order to investigate the impact on calculated performance.
Book Synopsis Transonic Flow Computation in Annular and Unsymmetric Two-Dimensional Nozzles by : H. Doyle Thompson
Download or read book Transonic Flow Computation in Annular and Unsymmetric Two-Dimensional Nozzles written by H. Doyle Thompson and published by . This book was released on 1973 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical model has been formulated and a computer program has been developed to compute the transonic flow field in either two-dimensional or annular axisymmetric nozzles. The analytical model assumes the inviscid, irrotational flow of a perfect gas, and is based on a Taylor series expansion around a Mach number of unity. An expansion parameter, epsilon is defined in terms of the wall geometry at the minimum area cross section. The method is capable of treating unsymmetric wall geometries. First, second, or third order solutions can be obtained from the computer program. (Modified author abstract).

Book Synopsis Computational Study of Axisymmetric Off-Design Nozzle Flows by : National Aeronautics and Space Administration (NASA)
Download or read book Computational Study of Axisymmetric Off-Design Nozzle Flows written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-20 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational Fluid Dynamics (CFD) analyses of axisymmetric circular-arc boattail nozzles operating off-design at transonic Mach numbers have been completed. These computations span the very difficult transonic flight regime with shock-induced separations and strong adverse pressure gradients. External afterbody and internal nozzle pressure distributions computed with the Wind code are compared with experimental data. A range of turbulence models were examined, including the Explicit Algebraic Stress model. Computations have been completed at freestream Mach numbers of 0.9 and 1.2, and nozzle pressure ratios (NPR) of 4 and 6. Calculations completed with variable time-stepping (steady-state) did not converge to a true steady-state solution. Calculations obtained using constant timestepping (timeaccurate) indicate less variations in flow properties compared with steady-state solutions. This failure to converge to a steady-state solution was the result of using variable time-stepping with large-scale separations present in the flow. Nevertheless, time-averaged boattail surface pressure coefficient and internal nozzle pressures show reasonable agreement with experimental data. The SST turbulence model demonstrates the best overall agreement with experimental data.

Book Synopsis Flow Field Analysis of a Nozzle-Boattail System by : Stephen A. Pasley
Download or read book Flow Field Analysis of a Nozzle-Boattail System written by Stephen A. Pasley and published by . This book was released on 1974 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: A production type computer program has been developed which is capable of analyzing the supersonic flow fields associated with aximmetric nozzle-base-boattail assemblies. Using the method of characteristics, an analysis for both the nozzle and boattail flow fields was developed. The analysis is based on the governing gas dynamic equations for a rotational flow of a frozen or equilibrium gas mixture. The transonic method developed by Kliegel was used to obtain the initial-value line for the nozzle flow field analysis. If desired, axisymmetric tabular data can be input for the nozzle initial-value line. Either uniform flow or axisymmetric tabular data can be used to specify the initial-value line for the boattail flow field analysis. The nozzle and boattail contours can be specified as conical, second-order polynomial or tabular contours. (Author).

Book Synopsis Laminar Flow-field Computation in Axisymmetric Nozzles by : B. C. Barber
Download or read book Laminar Flow-field Computation in Axisymmetric Nozzles written by B. C. Barber and published by . This book was released on 1977 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: A numerical procedure for computing the laminar flow-field in nozzles at throat Reynolds numbers of 300-3000 is described. Such nozzles are found in spacecraft position control thrusters, chemical lasers, and low density hypersonic wind-tunnels. A parabolic approximation of the Navier-Stokes equations (the boundary layer equations) is transformed to Von Mises form and solved numerically by a central difference method. The entire subsonic and supersonic flow-field is computed. No assumptions or approximations, other than those inherent in the flow equations, are involved. The method is of the direct type and the flow-field for any given nozzle geometry may, in principle, be computed. Examples are given comparing computed results with published experimental data.
