This book was released on 1964 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results are presented for an experimental study of Taylor vortices and turbulence in the flow between a rotating inner cylinder and both concentric and eccentric stationary outer cylinders. The results include: 1). measurement of the critical speed for onset of Taylor vortices as function of the eccentricity of the cylinders, 2). visual study of the flow up to a Reynolds number of 40,000, 3). measurement of the friction factor for the flow up to a Reynolds number of number of 40,000, 4). study of the effect of axial flow on the critical speed for onset of Taylor vortices. 5). preparation of design charts for calculating friction loss in concentric and eccentric journal bearings, operating in super-laminar flow regime.--Author.

This book was released on 2001-08-28 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book springs from the programme Quantized Vortex Dynamics and Sup- ?uid Turbulence held at the Isaac Newton Institute for Mathematical Sciences (University of Cambridge) in August 2000. What motivated the programme was the recognition that two recent developments have moved the study of qu- tized vorticity, traditionally carried out within the low-temperature physics and condensed-matter physics communities, into a new era. The ?rst development is the increasing contact with classical ?uid dynamics and its ideas and methods. For example, some current experiments with - lium II now deal with very classical issues, such as the measurement of velocity spectra and turbulence decay rates. The evidence from these experiments and many others is that super?uid turbulence and classical turbulence share many features. The challenge is now to explain these similarities and explore the time scales and length scales over which they hold true. The observed classical aspects have also attracted attention to the role played by the ?ow of the normal ?uid, which was somewhat neglected in the past because of the lack of direct ?ow visualization. Increased computing power is also making it possible to study the coupled motion of super?uid vortices and normal ?uids. Another contact with classical physics arises through the interest in the study of super?uid vortex - connections. Reconnections have been studied for some time in the contexts of classical ?uid dynamics and magneto-hydrodynamics (MHD), and it is useful to learn from the experience acquired in other ?elds.

Available in PDF, EPUB and Kindle. Book excerpt: Measurements have been made at two rotational speeds of the mean motion and turbulence levels within a shallow vortex chamber that has a rotating porous wall as an outer boundary. Very nominal levels of turbulence (2 to 3 per cent) were observed on the central plane of these vortices while a significant portion of the mass flow through the vortex was observed to pass through the end wall boundary layers. A fairly high level of turbulence was then introduced into this vortex chamber by means of a grid of axially aligned bars at the outer rim of the vortex. This high level of turbulence was observed to decay rapidly to a relative level of intensity of about 6 percent, indicating that for tangential Reynolds numbers up to at least 100000, the flow with a driven vortex is stable with respect to the introduction of turbulence. The results obtained corroborate Kendall's findings, namely that the primary cause of the degradation of the performance of a confined vortex is the leakage of mass flux through the boundary layers on the end walls of the vortex chamber.
