Book excerpt: Goertler vortices are thought to be the cause of transition in many fluid flows of practical importance. A review of the different stages of vortex growth is given. In the linear regime, nonparallel effects completely govern this growth, and parallel flow theories do not capture the essential features of the development of the vortices. A detailed comparison between the parallel and nonparallel theories is given and it is shown that at small vortex wavelengths, the parallel flow theories have some validity; otherwise nonparallel effects are dominant. New results for the receptivity problem for Goertler vortices are given; in particular vortices induced by free stream perturbations impinging on the leading edge of the walls are considered. It is found that the most dangerous mode of this type can be isolated and it's neutral curve is determined. This curve agrees very closely with the available experimental data. A discussion of the different regimes of growth of nonlinear vortices is also given. Again it is shown that, unless the vortex wavelength is small, nonparallel effects are dominant. Some new results for nonlinear vortices of 0(1) wavelengths are given and compared to experimental observations. Hall, Philip Unspecified Center...

Book Synopsis Secondary Instabilities of Görtler Vortices in High-Speed Boundary Layers by : Jie Ren
Download or read book Secondary Instabilities of Görtler Vortices in High-Speed Boundary Layers written by Jie Ren and published by Springer. This book was released on 2017-10-27 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis first reveals the mechanism of Görtler instabilities and then demonstrates how transitions at hypersonic flows can be effectively controlled (either promoted or suppressed) with Görtler or Klebanoff modes. It focuses on understanding and controlling flow transitions from mild laminar to fully turbulent flows at high speeds—aspects that have become crucial at the dawn of an incredible era, in which hypersonic vehicles are becoming available. Once this occurs, it will be possible to travel from Beijing to Los Angeles within just 2 hours, and we will all live in a genuinely global village—and not just virtually, but physically. Görtler instabilities have often been used to promote flow transition in hypersonic vehicles. However, how Görtler instabilities are excited and how they evolve in hypersonic flows are questions that have yet to be answered.

This book was released on 1996-03-22 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Market: Those interested in fluid dynamics and the related fields of oceanography, meteorology, and mechanical, aerospace, chemical, and civil engineering. This monograph is a report of a meeting sponsored by the National Science Foundation to determine research trends and consequent funding/research needs in fluid dynamics. The book covers major industries, technologies, and environmental issues affected by fluid mechanics, as well as the direction future research in the field should take. The areas covered not only fill important gaps in the literature, they are crucial to the resolution of serious global and regional environmental problems. In addition, the book emphasizes the impact of the research areas on commercial questions and on issues affecting public policy.
