This book was released on 2022-01-18 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental investigation in turbulent boundary layer flows represents one of the canonical geometries of wall bounded shear flows. Utmost relevance of such experiments, however, is applied in the engineering applications in aerospace and marine industries. In particular, continuous effort is being imparted to explore the underlying physics of the flow in order to develop models for numerical tools and to achieve flow control. Flow control experiments have been widely investigated since 1930’s. Several flow control technique has been explored and have shown potential benefit. But the choice of control technique depends largely on the boundary condition and the type of application. Hence, friction drag of subsonic transport aircraft is intended to be reduced within the scope of this Ph. D. topic. Therefore, application of active control method such as microblowing effect in the incompressible, zero pressure gradient turbulent boundary layer was investigated. A series of experiments have been performed in two different wind tunnel facilities. Wind tunnel from Department of Aerodynamics and Fluid Mechanics (LAS) was used for the measurements for moderate Reynolds number range in co-operation with the wind tunnel from Laboratoire de M´ecanique de Feiret Lille for large Reynolds number range. Measurements are conducted with the help of state-of-the-art techniques such as Laser Doppler Anemometry, Particle Image Velocimetry and electronic pressure sensors.

S. Longobardo and published by . This book was released on 1962 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Velocity and temperature data were obtained for the annulus between a rotating inner cylinder and a stationary outer cylinder. The data were obtained for air under circumstances such that appreciable variation of the transport properties and density would occur in a turbulent flow. These data make possible a test of current theories for the behavior of turbulent, variable-property flow. (Author).

Download or read book An Introduction to Turbulent Flow written by Jean Mathieu and published by Cambridge University Press. This book was released on 2000-06-26 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most natural and industrial flows are turbulent. The atmosphere and oceans, automobile and aircraft engines, all provide examples of this ubiquitous phenomenon. In recent years, turbulence has become a very lively area of scientific research and application, attracting many newcomers who need a basic introduction to the subject. An Introduction to Turbulent Flow, first published in 2000, offers a solid grounding in the subject of turbulence, developing both physical insight and the mathematical framework needed to express the theory. It begins with a review of the physical nature of turbulence, statistical tools, and space and time scales of turbulence. Basic theory is presented next, illustrated by examples of simple turbulent flows and developed through classical models of jets, wakes, and boundary layers. A deeper understanding of turbulence dynamics is provided by spectral analysis and its applications. The final chapter introduces the numerical simulation of turbulent flows. This well-balanced text will interest graduate students in engineering, applied mathematics, and the physical sciences.
Download or read book An Experimental Study of the Decay of Turbulent Energy in Several Gases and at High and Low Density written by Wilmot Hyde Webb and published by . This book was released on 1962 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: A hot-wire anemometer study of the decay of turbulent energy downstream of a grid in atmospheric pressure air, argon and helium and at several ambient pressure levels in air was carried out. A variable density low speed blowdown tunnel was employed which was operated over the range 0.2 to 8 atmospheres pressure. It was found in the decay measurements that above a grid Reynolds number, RM, of about 2,000 and at atmospheric pressure and above, an identical initial period decay law occurred independent of the gas employed or the ambient pressure level. There was no evidence indicating the invalidity of the continuum view of turbulence for this range. For RM below 1,000 or at low ambient pressure, however, a decrease in the normal turbulence intensity was found, the magnitude of which appeared to depend on the pressure level and the gas employed.
