Available in PDF, EPUB and Kindle. Book excerpt: The aerodynamics of aircraft at high angles of attack is a subject which is being pursued diligently, because the modern agile fighter aircraft and many of the current generation of missiles must perform well at very high incidence, near and beyond stall. However, a comprehensive presentation of the methods and results applicable to the studies of the complex aerodynamics at high angle of attack has not been covered in monographs or textbooks. This book is not the usual textbook in that it goes beyond just presenting the basic theoretical and experimental know-how, since it contains reference material to practical calculation methods and technical and experimental results which can be useful to the practicing aerospace engineers and scientists. It can certainly be used as a text and reference book for graduate courses on subjects related to high angles of attack aerodynamics and for topics related to three-dimensional separation in viscous flow courses. In addition, the book is addressed to the aerodynamicist interested in a comprehensive reference to methods of analysis and computations of high angle of attack flow phenomena and is written for the aerospace scientist and engineer who is familiar with the basic concepts of viscous and inviscid flows and with computational methods used in fluid dynamics.

Available in PDF, EPUB and Kindle. Book excerpt: The cause of the phenomenon of steady asymmetric flow on cones at moderately high angles of attack is the subject of this investigation. At very higher angles of attack, the flow will become unsteady with a Karman vortex street being shed downstream. This second phenomenon was not considered in the current research project. The investigation used computational fluid dynamics as a tool to uncover the fundamental cause of asymmetric separated flows. The appearance of new flow features as the critical angle of attack was approached was studied in detail. Isolating asymmetric disturbances to specific portions of the flow was also attempted. The stability of the symmetric flow above the critical angle of attack was investigated analytically. The transition of the flow from symmetric to asymmetric as the computation was continued was studied in detail. All of these studies indicated that the interaction of the vortices in the cross flow plane results in an instability in the symmetric flow. In addition, the interaction between the vortices seems to be somewhat global in nature.

Download or read book Vorticity and Vortex Dynamics written by Jie-Zhi Wu and published by Springer Science & Business Media. This book was released on 2007-04-20 with total page 776 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive and intensive monograph for scientists, engineers and applied mathematicians, as well as graduate students in fluid dynamics. It starts with a brief review of fundamentals of fluid dynamics, with an innovative emphasis on the intrinsic orthogonal decomposition of fluid dynamic process, by which one naturally identifies the content and scope of vorticity and vortex dynamics. This is followed by a detailed presentation of vorticity dynamics as the basis of later development. In vortex dynamics part the book deals with the formation, motion, interaction, stability, and breakdown of various vortices. Typical vortex structures are analyzed in laminar, transitional, and turbulent flows, including stratified and rotational fluids. Physical understanding of vertical flow phenomena and mechanisms is the first priority throughout the book. To make the book self-contained, some mathematical background is briefly presented in the main text, but major prerequisites are systematically given in appendices. Material usually not seen in books on vortex dynamics is included, such as geophysical vortex dynamics, aerodynamic vortical flow diagnostics and management.

Download or read book Analysing Structure in Academic Writing written by Tomoko Sawaki and published by Springer. This book was released on 2016-09-14 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book breaks through formalistic traditions to propose a new generic structure analytical framework for academic writing. The integrated approach, taking lessons from cognitive linguistics and structuralism, offers a foundation for establishing research and pedagogy that can promote diversity and inclusion in academia. The simplicity of the flexible structure analytical model proposed by Sawaki enables the user to analyse diverse instances of genre. Further innovation is made in the analysis of generic structure components by integrating George Lakoff and Mark Johnson’s metaphor analysis method, so that the model can account for cultural and ideological patterns that structure our abstract thinking. Using these integrations, the author has established a structure analytical model that can take into account linguistic, cognitive, and pragmatic aspects of genre. Researchers in the fields of linguistics, discourse studies, cultural studies, education, and English for Academic Purposes will be able to use this model to identify whether an atypical instance in academic texts is a result of the writer’s individual failure or a failure to understand diversity in academic writing.

This book was released on 1975 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Linear regression techniques are used to establish a quantitative description of side forces on bodies at high incidence. A data base is assembled concerning the key side force characteristics of maximum observed side force, angle of occurrence, and minimum angle of attack at which a side force is observed. This information is examined to determine the important trends and a predictive model for side force based on the crossflow analogy is developed to suggest other important variables. A linear regression model for these quantities is developed to include only those variables which are statistically significant. Results indicate that peak side force coefficients are a function of Mach number and only weakly of Reynolds number. Nose fineness is the critical model dimension which suggests that peak side force is a product of the nose flow field. The angle at which peak side forces occur is found to be dependent on model length and Mach number, while the onset angle of attack is a function of model length only.
