Book Synopsis Gas Transfer at Water Surfaces by : W. Brutsaert
Download or read book Gas Transfer at Water Surfaces written by W. Brutsaert and published by Springer Science & Business Media. This book was released on 1983-12-31 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transfer across the surface of environmental waters is of interest as an important phase in the geophysical and natural biochemical cycles of numer ous substances; indeed it governs the transition, one way or the other, be tween the dissolved state in the water and the gaseous state in the atmo sphere. Especially with increasing population and industrialization, gas transfer at water surfaces has become a critical factor in the understanding of the various pathways of wastes in the environment and of their engineering management. This interfacial mass transfer is, by its very nature, highly complex. The air and the water are usually in turbulent motion, and the interface be tween them is irregular, and disturbed by waves, sometimes accompanied by breaking, spray and bubble formation. Thus the transfer involves a wide variety of physical phenomena occurring over a wide range of scales. As a consequence, scientists and engineers from diverse disciplines and problem areas, have approached the problem, often with greatly differing analytical and experimental techniques and methodologies.
Book Synopsis Structure of Turbulent Free-convection Boundary Layers Along a Vertical Plate by : K. T. Yang
Download or read book Structure of Turbulent Free-convection Boundary Layers Along a Vertical Plate written by K. T. Yang and published by . This book was released on 1969 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: A non-local differential phenomenological theory for turbulent free-convection boundary layers along a two-dimensional heated vertical plate is described, in which both eddy viscosity and eddy thermal diffusivity are considered unknown. The total viscosity (molecular plus eddy) is taken to be governed by a parabolic rate equation which takes into account turbulent convection, diffusion, generation and decay, while the turbulent thermal diffusivity is based on a constant turbulent Prandtl number. Based on this closed system of partial differential equations, the mean velocity and temperature field as well as the eddy viscosity and the turbulent thermal diffusivity distribution can be mapped out. It is shown for the vertical-plate problem that the generation of turbulence is essentially shear induced, and that the gravity force only influences the mean velocity and temperature fields. A degenerated local theory is developed to interpret and compare with existing experimental data. Calculations show that the turbulent free-convection boundary layer consists essentially of three distinct regions, namely, the viscous sublayer, the inner layer, and the outer layer. The viscous sublayer defined by vanishing eddy viscosity, is shown to have a nonlinear velocity distribution. The inner layer is dominated by the balance of turbulent generation and decay. The outer layer is governed mainly by turbulent convection and diffusion. It is shown that Corrsin's viscous superlayer also exists in the turbulent free-convection case and that temperature fluctuations tend to reduce the sharpness of the turbulent-non-turbulent interface. It has also been found that Grashof number has strong effects on turbulent generation and decay. (Author).

Book Synopsis What is fluid turbulence? by : Gert Naue
Download or read book What is fluid turbulence? written by Gert Naue and published by TWENTYSIX. This book was released on 2018-07-19 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an innovative wave structure theory of turbulence. The most important advancement is the provision of turbulence parameters of the optimal self-organization of turbulence from theoretical investigations via information entropy assessments. The new theoretical results are in very good agreement with the experimentally confirmed results of turbulent convection velocity fields at free and forced turbulence. In connection with the logarithmic wall law, it is shown that there is no viscous sublayer. The formulation of the oscillation problem of turbulence and the solution of boundary value tasks with coordinate systems adapted to the specific task are provided for many technically significant turbulent flows, including smooth and rough pipe flow, confusor and diffuser flow, swirl flow, stirrer flow, inlet flow, intermittency, wake flow and free jets. An epistemological component of the innovation is the representation of turbulence by con-travariant vector fields which are characterized by the stability of the turbulence structures at changed structural density. The turbulence structures act as active momentum transmitters of refracted monopoles, dipoles, tripoles and quadrupoles in the flow field. The dissipation mechanism with regard to the processes in turbulence structures is, for the first time, qualita-tively and quantitatively described. The transition from the contravariant turbulence velocity field to the covariant convection velocity field induce refraction and entanglement. The principles of turbulence act as fractal principle, reflection principle, entanglement principle, refractive principle and convolution principle. The wave structure theory of turbulence provides an arraying tool for further investigations into numerous open problems.
Book Synopsis An Informal Introduction to Turbulence by : A. Tsinober
Download or read book An Informal Introduction to Turbulence written by A. Tsinober and published by Springer Science & Business Media. This book was released on 2001-11-30 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an informal introduction to the turbulence of fluids. The emphasis is placed on turbulence as a physical phenomenon. It addresses the unresolved issues, misconceptions, controversies, and major problems of the turbulence of fluids rather than the conventional formalistic elements and models. Little use is made of complicated formalisms; instead the emphasis is placed on an essentially informal qualitative form. The scope of the book is focused on the purely basic aspects of the turbulent flows of incompressible fluids. This book will certainly be of interest and use to graduate students as well as scientists active in fields where the turbulence of fluids is of importance. The book is intentionally written to appeal to a broad readership with the aim of making the turbulence of fluids interesting and comprehensible to the interested engineer.

Book Synopsis Development of Experimental Techniques and Studies of Spatial Structure in Turbulent Thermal Convection by : Peter William Offutt
Download or read book Development of Experimental Techniques and Studies of Spatial Structure in Turbulent Thermal Convection written by Peter William Offutt and published by . This book was released on 1995 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Particle-image velocimetry (PIV), shadowgraph, and thermochroic liquid crystal techniques are applied to the study of spatial structure of turbulent thermal convection in wide horizontal water layers. A large-aspect-ratio test section for the study of turbulent Rayleigh convection in water has been constructed, instrumented and characterized. Boundary temperature measurements reveal significant finite Biot number effects for water bounded by aluminum. Particle-image velocimetry measurements in a vertical plane in Rayleigh convection gave approximately 8500 velocity vectors in each of 62 instantaneous realizations at a Rayleigh number of 1.0 $times$ 10$sp{8}$. The vector fields reveal structures ranging in size from a few millimeters in the boundary regions to large-scale motions spanning the 10 cm layer depth. Ensemble one-point statistics of the velocity field, including the mean velocity field, root-mean-square profiles, and probability-density functions of the vertical velocity as a function of height are presented. The PIV data have also provided the first measurements of the two-point spatial velocity correlation in turbulent Rayleigh convection. The PIV measurements are supplemented by thermochroic liquid crystal visualizations of temperature fields on the lower boundary, and by shadowgraph projections of the temperature fields in the bulk. The shadowgraphs reveal well-defined, viscous thermal plumes which generally cross the layer intact; midlayer transit measurements from videotaped shadowgraphs in Rayleigh convection and unsteady nonpenetrative convection give ascent rates of 1.4 to 1.5 times Deardorff's inviscid convective velocity scale. The thermochroic boundary temperature visualizations showed plumes emanating from nodes in a network of warm lines enclosing patches of cooler fluid. Deardorff's inviscid velocity and temperature scales for the core are refined by enforcing equality of bulk turbulent production and spectral energy transfer. The collapse of velocity fluctuation data under the new "bulk" scales for different modes of turbulent thermal convection shows the old systematic discrepancies arose from dimensionally correct but numerically arbitrary scale definitions. Also, under the new scaling, a monotonic Rayleigh number dependence emerges among the core temperature fluctuation profiles. This trend indicates that true high-Reynolds-number invariance is not achieved at Rayleigh numbers accessible to direct numerical simulation and laboratory-scale experiments.
