This book was released on 2018-07-18 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The efficient multilevel adaptive method has been successfully applied to perform direct numerical simulations (DNS) of flow transition in 3-D channels and 3-D boundary layers with 2-D and 3-D isolated and distributed roughness in a curvilinear coordinate system. A fourth-order finite difference technique on stretched and staggered grids, a fully-implicit time marching scheme, a semi-coarsening multigrid method associated with line distributive relaxation scheme, and an improved outflow boundary-condition treatment, which needs only a very short buffer domain to damp all order-one wave reflections, are developed. These approaches make the multigrid DNS code very accurate and efficient. This allows us not only to be able to do spatial DNS for the 3-D channel and flat plate at low computational costs, but also to do spatial DNS for transition in the 3-D boundary layer with 3-D single and multiple roughness elements, which would have extremely high computational costs with conventional methods. Numerical results show good agreement with the linear stability theory, the secondary instability theory, and a number of laboratory experiments. The contribution of isolated and distributed roughness to transition is analyzed.

Book Synopsis Computational Fluid Dynamics Review 1998 (In 2 Volumes) by : Mohamed M Hafez
Download or read book Computational Fluid Dynamics Review 1998 (In 2 Volumes) written by Mohamed M Hafez and published by World Scientific. This book was released on 1998-11-20 with total page 1169 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first volume of CFD Review was published in 1995. The purpose of this new publication is to present comprehensive surveys and review articles which provide up-to-date information about recent progress in computational fluid dynamics, on a regular basis. Because of the multidisciplinary nature of CFD, it is difficult to cope with all the important developments in related areas. There are at least ten regular international conferences dealing with different aspects of CFD.It is a real challenge to keep up with all these activities and to be aware of essential and fundamental contributions in these areas. It is hoped that CFD Review will help in this regard by covering the state-of-the-art in this field.The present book contains sixty-two articles written by authors from the US, Europe, Japan and China, covering the main aspects of CFD. There are five sections: general topics, numerical methods, flow physics, interdisciplinary applications, parallel computation and flow visualization. The section on numerical methods includes grids, schemes and solvers, while that on flow physics includes incompressible and compressible flows, hypersonics and gas kinetics as well as transition and turbulence. This book should be useful to all researchers in this fast-developing field.

Download or read book Wave Evolution and Laminar-turbulent Transition in Fully 3D Supersonic Flows written by Thorwald Herbert and published by . This book was released on 1996 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of transition in fully three-dimensional boundary layers on high-speed aircraft is hampered by the lack of a rigorous theory of instability in these flows and the lack of accurate data to evaluate approximations. To provide such data, we have in this first phase of a longer-term effort designed a computational framework for this task. This framework allows interactive computations and data analysis in connected blocks of the large physical domain on networks of computers. Theoretical studies on the stability of three-dimensional boundary layers have been performed to obtain guidance on the computational treatment of the problem. A multi-grid method specially adapted to the analysis of wave propagation in shallow domains has been developed and implemented. Testing of the code could not be completed before the project was terminated.
