Development Of Unstructured Grid Methods For Steady And Unsteady Aerodynamic Analysis

Download or read book Development of Unstructured Grid Methods for Steady and Unsteady Aerodynamic Analysis written by National Aeronautics and Space Adm Nasa and published by Independently Published. This book was released on 2019 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current status of the development of unstructured grid methods in the Unsteady Aerodynamics Branch at NASA-Langley is described. These methods are being developed for steady and unsteady aerodynamic applications. The flow solvers that were developed for the solution of the unsteady Euler and Navier-Stokes equations are highlighted and selected results are given which demonstrate various features of the capability. The results demonstrate 2-D and 3-D applications for both steady and unsteady flows. Comparisons are also made with solutions obtained using a structured grid code and with experimental data to determine the accuracy of the unstructured grid methodology. These comparisons show good agreement which thus verifies the accuracy. Batina, John T. Langley Research Center NASA-TM-102730, NAS 1.15:102730, ICAS-90-6.9.4 RTOP 505-63-50-12...
