Book Synopsis Research on Topics in Transonic Flow Theory and Adaptive Grid Generation by : D. Nixon
Download or read book Research on Topics in Transonic Flow Theory and Adaptive Grid Generation written by D. Nixon and published by . This book was released on 1983 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes work concerned with some topics connected with a transonic flow theory and also some problems in adaptive mesh procedures. The work on adaptive mesh procedures is concerned with the development of adaptive mesh strategies and solution procedures for highly clustered adaptive meshes. It has been found that the strong conservation law form of the governing equations in computational variables cannot capture the shock waves correctly for arbitrary clustering. Methods for correcting this problem have been investigated. The work on transonic flow theory is concerned with the existence of multiple solutions in full potential calculations. Since the full potential equation is difficult to analyze compared with small disturbance equation, multiple solutions have been found using transonic small disturbance theory. These results have been analyzed using the transonic integral equation theory and indicate that the transonic potential theory is not formulated uniquely.

Book Synopsis A New Solution-Adaptive Grid Generation Method for Transonic Airfoil Flow Calculations by : National Aeronautics and Space Administration (NASA)
Download or read book A New Solution-Adaptive Grid Generation Method for Transonic Airfoil Flow Calculations written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-21 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The clustering algorithm is controlled by a second-order, ordinary differential equation which uses the airfoil surface density gradient as a forcing function. The solution to this differential equation produces a surface grid distribution which is automatically clustered in regions with large gradients. The interior grid points are established from this surface distribution by using an interpolation scheme which is fast and retains the desirable properties of the original grid generated from the standard elliptic equation approach.

Book Synopsis Analysis of Three-Dimensional Transonic Potential Flows Using Optimum Grid by : A. Ecer
Download or read book Analysis of Three-Dimensional Transonic Potential Flows Using Optimum Grid written by A. Ecer and published by . This book was released on 1982 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: A three-dimensional finite element procedure is developed for the analysis of three-dimensional transonic flows and applied to the analysis of wing-body combinations. A finite element grid generation scheme for three-dimensional bodies with complex geometries is presented. The design of efficient, body-fitted computational grids with isoparametric mappings, as well as the application of higher-order finite elements in analyzing transonic potential flows are investigated. Two different computational grids were designed and studied with a numerical scheme based on the density upwinding in the supersonic regions. A pseudo-unsteady type formulation is employed in determining a steady-state solution. It is concluded that the grid generation scheme is quite flexible and efficient for generating solution adaptive grids and providing local refinements in the sensitive flow regions. Also, it is shown that the employed numerical scheme with higher-order elements at flow regions of high gradients produced results which compare favorable with experimental data. (Author).

Book Synopsis Shallow Water Hydrodynamics by : W.Y. Tan
Download or read book Shallow Water Hydrodynamics written by W.Y. Tan and published by Elsevier. This book was released on 1992-08-17 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within this monograph a comprehensive and systematic knowledge on shallow-water hydrodynamics is presented. A two-dimensional system of shallow-water equations is analyzed, including the mathematical and mechanical backgrounds, the properties of the system and its solution. Also featured is a new mathematical simulation of shallow-water flows by compressible plane flows of a special virtual perfect gas, as well as practical algorithms such as FDM, FEM, and FVM. Some of these algorithms have been utilized in solving the system, while others have been utilized in various applied fields. An emphasis has been placed on several classes of high-performance difference schemes and boundary procedures which have found wide uses recently for solving the Euler equations of gas dynamics in aeronautical and aerospatial engineering. This book is constructed so that it may serve as a handbook for practicians. It will be of interest to scientists, designers, teachers, postgraduates and professionals in hydraulic, marine, and environmental engineering; especially those involved in the mathematical modelling of shallow-water bodies.
