This book was released on 2014 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bottom propagating gravity currents resulting from full- and partial-depth lock-release experiments are investigated as they propagate up a rising slope in uniform and two-layer stratified ambients. In the case of uniform ambients, the gravity current front decelerates in a nearly uniform manner along the slope at a rate that agrees with theoretical predictions. The shape of the gravity current as it decelerates over relatively steep slopes is found to be self-similar with a nearly linear decrease of the head height between the start of the slope and up to 80\% of the distance to the nose. Some deviation from self-similar behaviour is found in cases with small slopes because of the comparatively large volume of fluid in the gravity current tail that flows downslope while the front continues to advance upwards. In the case of two-layer ambients, the initial gravity current front speed is found to be consistent with a theory adapted from \cite{shin_dalziel_linden2004}. The subsequent evolution depends on the gravity current speed relative to the speed of the interfacial disturbance it creates. The deceleration of supercritical gravity currents, which travel faster than the interfacial disturbance, is gradual and agrees well with the relationship developed for upslope gravity currents in uniform density ambients and modified for a two-layer ambient. In most subcritical cases the gravity current suddenly comes to rest as a consequence of interactions with the interfacial disturbance. The disturbance amplitude, speed, and width are found to be nearly constant during its evolution. In cases for which the ambient interface intersected the tank bottom, the amplitude, speed, and width are nearly constant up to the point where the lower layer shallowed and the disturbance transformed into an upslope propagating gravity current.

Download or read book Gravity Currents written by John E. Simpson and published by . This book was released on 1987 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This explanation of the nature of gravity currents (Bouyancy-driven flows in fluids) and their manifestations in the atmosphere, the oceans and the earth sciences, fills a serious gap in the literature. It will also benefit a great many workers in other scientific disciplines, who will be able to apply the principles of gravity currents to their own specialist subject. Much of the work has not previously been published, and the publishers know of no other book with a similar range of information. The author's own work in the development of a variety of laboratory experiments designed to offer an understanding of the physical processes, is made very clear to the reader, illustrating a range of phenomena which are important in areas as diverse as aircraft safety, the distribution of airborne pests, and airborne pollution. The study of oceans ranges from the Gulf Stream to river fronts in lakes and fjords, where the formation of a front is of biological importance. In a section on avalanche flows, avalanches of snow, rock, and volcanic eruptions, are also shown to be gravity currents of vital significance. Factors influencing the behaviour of gravity currents are reviewed. The topics are dealt with in numerous laboratory experiments, and only simple mathematics is included. A final chapter reviews the growing subject of numerical models of gravity currents.

This book was released on 2020-12-08 with total page 815 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flow of gravity currents and intrusions is a subject of active research and engineering application. Currently, there are no formal teaching courses for this topic. Materials and information available in the market are scattered and dated. Researchers and engineers face difficulties in acquiring the 'state-of-the-art' knowledge. The book bridges this gap between the need and supply of the relevant insight and know-how.Written by a renowned author who is a recognized authority in the field, this unique compendium assembles the relevant knowledge into a systematic and unified framework. The presentation is gradual from the elementary to the frontier, and accessible to readers with only a basic background in fluid mechanics and applied mathematics. This will facilitate the systematic acquirement and application of available knowledge to both practical problems and further research.This must-have volume is a useful monograph — that can also serve as a textbook in advanced courses — for researchers, students, engineers and applied mathematicians in the fields of civil engineering, hydraulic engineering, mechanical engineering, ocean engineering and environmental engineering.

Download or read book Thermally-driven Mesoscale Flows and their Interaction with Atmospheric Boundary Layer Turbulence written by Jon Ander Arrillaga Mitxelena and published by Springer Nature. This book was released on 2020-06-11 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents developments of novel techniques and applies them in order to understand the interactions between thermally driven mesoscale flows (sea and mountain breezes) and the turbulent exchange within the atmospheric boundary layer. These interactions are not accurately reproduced in the meteorological models currently employed for weather forecasting. Consequently, important variables such as air temperature and wind speed are misrepresented. Also, the concentrations of relevant greenhouse gases such as CO2 are considerably affected by these interactions. By applying a systematic algorithm based on objective criteria (presented here), the thesis explores complete observational databases spanning up to 10 years. Further, it presents statistically significant and robust results on the topic, which has only been studied in a handful of cases in the extant literature. Lastly, by applying the algorithm directly to the outputs of the meteorological model, the thesis helps readers understand the processes discussed and reveals the biases in such models.

This book was released on 1989-01-01 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation This book provides an introduction to the vast subject of initial and initial-boundary value problems for PDEs, with an emphasis on applications to parabolic and hyperbolic systems. The Navier-Stokes equations for compressible and incompressible flows are taken as an example to illustrate the results. Researchers and graduate students in applied mathematics and engineering will find Initial-Boundary Value Problems and the Navier-Stokes Equations invaluable. The subjects addressed in the book, such as the well-posedness of initial-boundary value problems, are of frequent interest when PDEs are used in modeling or when they are solved numerically. The reader will learn what well-posedness or ill-posedness means and how it can be demonstrated for concrete problems. There are many new results, in particular on the Navier-Stokes equations. The direct approach to the subject still gives a valuable introduction to an important area of applied analysis.

Available in PDF, EPUB and Kindle. Book excerpt: The dynamics of flows in density-stratified fluids are an important topic for scientific enquiry. Flows arise in many contexts, ranging from industrial settings to the oceanic and atmospheric environments. Both the ocean and atmosphere are characterized by the basic vertical density stratification, and this feature can affect the dynamics on all scales ranging from the micro-scale to the planetary scale. This volume provides a state-of-the-art account of stratified flows as they are relevant to the ocean and atmosphere, with a primary focus on meso-scale phenomena; that is, phenomena whose time and space scales are such that the density stratification is a dominant effect, so that frictional and diffusive effects on the one hand and the effects of the earth's rotation on the other, can be regarded as of less importance. Environmental Stratified Flows is essential to researchers in the field of oceanography, coastal and marine engineering, and environmental fluid dynamics.
