This book was released on 1954 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study is made of the stability of laminar boundary-layer profiles on slightly curved walls relative to small disturbances that result from vortices whose axes are parallel to the principal direction of flow. The result is an eigenvalue problem by which, for a given undisturbed flow at a prescribed wall, the amplification or decay is computed for each Reynolds number and each vortex thickness. For neutral disturbances (zero amplification) a critical Reynolds number is determined for each vortex distribution. The numerical calculation produces amplified disturbances on concave walls only.

Book Synopsis Dreidimensionale Stoerungen in Der Grenzschict an Einer Konkaven Wand (Three-Dimensional Disturbances in the Boundary Layer Along a Concave Wall). by : H. Bippes
Download or read book Dreidimensionale Stoerungen in Der Grenzschict an Einer Konkaven Wand (Three-Dimensional Disturbances in the Boundary Layer Along a Concave Wall). written by H. Bippes and published by . This book was released on 1971 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of three-dimensional disturbances in the boundary layer along a concave wall was studied experimentally. Measurements of velocity distributions in the unstable boundary layer and of the amplification of small, forced, initial disturbances were made by photogrammetric evaluation of stereo-photographs. The flow was made visible by the hydrogen-bubble method. A comparison is made with the linearized theory. In the nonlinear part of the amplification, a secondary instability has been observed occurring in the longitudinal zones of low velocity U.A meandering motion ultimately leads to the laminar-to-turbulent transition.

Book excerpt: Coanda effect is a complex fluid flow phenomenon enabling the production of vertical take-off/landing aircraft. Other applications range from helicopters to road vehicles, from flow mixing to combustion, from noise reduction to pollution control, from power generation to robot operation, and so forth. Book starts with description of the effect, its history and general formulation of governing equations/simplifications used in different applications. Further, it gives an account of this effect’s lift boosting potential on a wing and in non-flying vehicles including industrial applications. Finally, occurrence of the same in human body and associated adverse medical conditions are explained.
Book Synopsis The Origin of Turbulence in Near-Wall Flows by : A.V. Boiko

This book was released on 2013-03-09 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Origin of Species Charles Darwin The origin of turbulence in fluids is a long-standing problem and has been the focus of research for decades due to its great importance in a variety of engineering applications. Furthermore, the study of the origin of turbulence is part of the fundamental physical problem of turbulence description and the philosophical problem of determinism and chaos. At the end of the nineteenth century, Reynolds and Rayleigh conjectured that the reason of the transition of laminar flow to the 'sinuous' state is in stability which results in amplification of wavy disturbances and breakdown of the laminar regime. Heisenberg (1924) was the founder of linear hydrody namic stability theory. The first calculations of boundary layer stability were fulfilled in pioneer works of Tollmien (1929) and Schlichting (1932, 1933). Later Taylor (1936) hypothesized that the transition to turbulence is initi ated by free-stream oscillations inducing local separations near wall. Up to the 1940s, skepticism of the stability theory predominated, in particular due to the experimental results of Dryden (1934, 1936). Only the experiments of Schubauer and Skramstad (1948) revealed the determining role of insta bility waves in the transition. Now it is well established that the transition to turbulence in shear flows at small and moderate levels of environmental disturbances occurs through development of instability waves in the initial laminar flow. In Chapter 1 we start with the fundamentals of stability theory, employing results of the early studies and recent advances.
