Book Synopsis Grid Generation by Elliptic Partial Differential Equations for a Tri-Element Augmentor-Wing Airfoil by : Reese L. Sorenson
Download or read book Grid Generation by Elliptic Partial Differential Equations for a Tri-Element Augmentor-Wing Airfoil written by Reese L. Sorenson and published by . This book was released on 1982 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Augmentor-Wing is a promising new development in airfoils for transport aircraft. It consists of a main airfoil with a slotted trailing-edge for blowing, and two smaller airfoils shrouding the blowing jet. Impressive short-takeoff-and-landing (STOL) results have been observed in flight, and both wind-tunnel tests and computational studies predict remarkably low drag in the cruise configuration. Two separate efforts to numerically simulate the flow about this airfoil in the cruise configuration are being pursued. One uses a unsteady viscous flow-solver, and the other a transonic full-potential approach. The inviscid full-potential approach will be used as a preliminary design tool to test a variety of configurations because of its relatively high speed; the viscous flow-solver will be used as a design verification tool to supplement experimental testing. The grid-generation program GRAPE has been adapted to satisfy the significantly different needs fo those two studies. The flow field is divided into zones, and continuity of grid lines and their slopes across zonal boundaries is assured. In addition, grid cell size and skewness at body boundaries is controlled. Thisnew application of grid generation by elliptic partial differential equations for this real-world, multielement problem is described. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Grid Generation is an outstanding text/reference designed to introduce students in applied mathematics, mechanical engineering, and aerospace engineering to structured grid generation. It provides excellent reference material for practitioners in industry, and it presents new concepts to researchers. Readers will learn what boundary-conforming grids are, how to generate them, and how to devise their own methods. The text is written in a clear, intuitive style that doesn't get bogged down in unnecessary abstractions. Topics covered include planar, surface, and 3-D grid generation; numerical techniques; solution adaptivity; the finite volume approach to discretization of hosted equations; concepts from elementary differential geometry; and the transformation of differential operators to general coordinate systems. The book also reviews the literature on algebraic, conformal, orthogonal, hyperbolic, parabolic, elliptic, biharmonic, and variational approaches to grid generation. This unique volume closes with the author's original methods of variational grid generation.

Book Synopsis Generation of Surface Grids Through Elliptic Partial Differential Equations for Aircraft and Missile Configurations by : Z. U. Warsi
Download or read book Generation of Surface Grids Through Elliptic Partial Differential Equations for Aircraft and Missile Configurations written by Z. U. Warsi and published by . This book was released on 1986 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical solution of the partial differential equations for the generation of surface grids requires a specification of the forcing function which depends on the geometry of the given surface. The data for the surface is usually in discrete form. Methods have been developed which fit a function over the given data. For complicated shapes, e.g., an airplane, the functional fit and the eventual grid generation for the fuselage and wings are done separately and then integrated later. Keywords: Grid generation; Curvilinear coordinates; Numerical methods; Computational fluid dynamics.

Available in PDF, EPUB and Kindle. Book excerpt: Computational Fluid Dynamics research, especially for aeronautics, continues to be a rewarding and industrially relevant field of applied science in which to work. An enthusiastic international community of expert CFD workers continue to push forward the frontiers of knowledge in increasing number. Applications of CFD technology in many other sectors of industry are being successfully tackled. The aerospace industry has made significant investments and enjoys considerable benefits from the application of CFD to its products for the last two decades. This era began with the pioneering work ofMurman and others that took us into the transonic (potential flow) regime for the first time in the early 1970's. We have also seen momentous developments of the digital computer in this period into vector and parallel supercomputing. Very significant advances in all aspects of the methodology have been made to the point where we are on the threshold of calculating solutions for the Reynolds-averaged Navier-Stokes equations for complete aircraft configurations. However, significant problems and challenges remain in the areas of physical modelling, numerics and computing technology. The long term industrial requirements are captured in the U. S. Governments 'Grand Challenge' for 'Aerospace Vehicle Design' for the 1990's: 'Massively parallel computing systems and advanced parallel software technology and algorithms will enable the development and validation of multidisciplinary, coupled methods. These methods will allow the numerical simulation and design optimisation of complete aerospace vehicle systems throughout the flight envelope'.

Book Synopsis Numerical grid generation and potential airfoil analysis and design by : Mato F. Siladic
Download or read book Numerical grid generation and potential airfoil analysis and design written by Mato F. Siladic and published by . This book was released on 1987 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this thesis is to explore the feasibility of using parabolic partial differential equation techniques for numerical grid generation for two-dimensional aerodynamic configurations. The contents include a discussion of grid generation concepts and schemes in the literature, iterative methods for numerical grid generation and two differential grid generation schemes: (1) an elliptic, and (2) a parabolic scheme. A detailed mathematical and numerical representation of both schemes is given. The main purpose in the treatment of the elliptic scheme is to introduce the necessary transformations to provide equations that will establish the particular parabolic scheme development. Surface singularity methods are found to be a good means for solution of potential flow problems. They can handle both single and multicomponent airfoils in analysis and design processes. The stream function approach appears to be very stable and a simple panel method applicable for practical initial analysis and design airfoil problems. The method provides reduction in the number of panels in comparison with other surface singularity methods and the best results were obtained with 40-60 panels per airfoil section. The modified approach for computing the actual position of the trailing edge provides designed airfoils with smooth shapes and stable design process. (edc).
Book Synopsis Marching Grid Generation Using Parabolic Partial Differential Equations by : S. Nakamura
Download or read book Marching Grid Generation Using Parabolic Partial Differential Equations written by S. Nakamura and published by . This book was released on 1982 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unique aspect of grid generation in computational fluid dynamics is that the grid generation equations have no physical meanings, so any equation may be used for this purpose if the grids generated are useful. This aspect provides a vast freedom in developing new methods of grid generation. This paper explores feasibility of using parabolic partial differential equations for grid generation. The advantages of using parabolic partial differential equations are as follows: (1) parabolic equations are initial value problems, so grids are generated by a marching algorithm like the hyperbolic grid generation method, (2) the parabolic partial differential equations have most properties of the elliptic equations, particularly the diffusion effect which smooths out any singularity of the inner boundary condition if any, and (3) the prescribed outer boundary conditions may be satisfied. The importance of the marching algorithm stated above is twofold: first, computational time required is only a very small fraction of that for the elliptic grid generation equations second, the fast-memory space required during grid generation can be substantially reduced from that required by the elliptic grid generation method. The authors consider the grid generation for a two-dimensional airfoil flow calculations for simplicity of discussions, although the method described in this paper is not restricted to two dimensions or airfoil problems.
