Available in PDF, EPUB and Kindle. Book excerpt: The use of unstructured, adaptive, embedded grids has been applied to hypersonic nonequilibrium CFD problems. Grid adaptation was accomplished by sub-dividing computational cells for 2-D and axisymmetric blunt body configurations. The high temperature gas mixture was described by Lighthill's dissociating gas model which was extended to include multiple coupled reaction paths in both viscous and inviscid flows. Ni's finite volume Lax-Wendroff scheme was used to integrate the governing equations. This algorithm was extended to include shock fitting and adaptation on general, unstructured, time dependent grids. The explicit real-gas algorithm and shock fitting procedure were validated by comparisons with experimental and computational results for perfect gas, dissociating gas, and multiple reaction cases. These comparisons also emphasized the importance of chemical length scale effects in predicting nonequilibrium gas behavior. Such effects were linked not only to species concentration profiles throughout the shock layer, but also to the excess production of Nitric Oxide frequently reported off the symmetry plane in reacting air blunt body flows. A detailed study of basic nonequilibrium flow phenomena has been completed for freestream Mach numbers from 10 to 15 over blunted cones and wedges. These flows demonstrated degrees of nonequilibrium ranging from nearly frozen to near equilibrium. In all cases the adaptive procedure correctly located and resolved perfect gas and nonequilibrium features. Adaptation was shown to be particularly useful in capturing the steep chemical gradients which appear within the shock layer. (jhd).

Download or read book Hypersonic Aerothermodynamics written by John J. Bertin and published by AIAA. This book was released on 1994 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: A modern treatment of hypersonic aerothermodynamics for students, engineers, scientists, and program managers involved in the study and application of hypersonic flight. It assumes an understanding of the basic principles of fluid mechanics, thermodynamics, compressible flow, and heat transfer. Ten chapters address: general characterization of hypersonic flows; basic equations of motion; defining the aerothermodynamic environment; experimental measurements of hypersonic flows; stagnation-region flowfield; the pressure distribution; the boundary layer and convective heat transfer; aerodynamic forces and moments; viscous interactions; and aerothermodynamics and design considerations. Includes sample exercises and homework problems. Annotation copyright by Book News, Inc., Portland, OR

Available in PDF, EPUB and Kindle. Book excerpt: Numerical procedures for solving the time-domain Maxwell equations based on the theory of characteristics were successfully developed. Both explicit and implicit methods were formulated by the time-central and spatial-windward algorithm to better describe wave motion. A new trapezoidal consistent implicit scheme was shown to be unconditionally stable for the linear initial value system and was able to generate numerical solutions comparable to those of the established explicit method. The formulation of the three-dimensional system including generalized coordinate system was completed but not explored. The present 2-D results on Cartesian frame demonstrated a potential for numerical efficiency improvement. Time-domain Maxwell equation, Trapezoidal consistent implicit scheme, Cartesian frame.

Download or read book Aerodynamics for Engineers written by John J. Bertin and published by Cambridge University Press. This book was released on 2021-08-12 with total page 843 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now reissued by Cambridge University Press, this sixth edition covers the fundamentals of aerodynamics using clear explanations and real-world examples. Aerodynamics concept boxes throughout showcase real-world applications, chapter objectives provide readers with a better understanding of the goal of each chapter and highlight the key 'take-home' concepts, and example problems aid understanding of how to apply core concepts. Coverage also includes the importance of aerodynamics to aircraft performance, applications of potential flow theory to aerodynamics, high-lift military airfoils, subsonic compressible transformations, and the distinguishing characteristics of hypersonic flow. Supported online by a solutions manual for instructors, MATLAB® files for example problems, and lecture slides for most chapters, this is an ideal textbook for undergraduates taking introductory courses in aerodynamics, and for graduates taking preparatory courses in aerodynamics before progressing to more advanced study.
