Book Synopsis Frazil Ice Dynamics by : Steven F. Daly
Download or read book Frazil Ice Dynamics written by Steven F. Daly and published by . This book was released on 1984 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: To describe the dynamic evolution of frazil ice in turbulent natural water bodies, the basic equation for dynamic frazil crystal number continuity and the basic equation of heat balance for a differential volume are developed. Crystal growth and nucleation of new crystals are the major parameters in these equations. Expressions for the growth rate of frazil ice crystals are described. The growth rate along the major axis is controlled by heat transfer. The heat transfer coefficient is a function of crystal size, the fluid turbulence, and the fluid properties. The magnitude of inertial and buoyancy forces on the ice crystals are determined as is their influence on the heat transfer. Spontaneous nucleation of ice can be discounted; secondary nucleation is responsible for the vast majority of frazil ice crystals. The theoretical rate of secondary nucleation is partially modeled as a function of the supercooling, fluid turbulence and crystal size distribution. A simple analytical solution of the basic equations is developed for the growth of frazil ice in a well-mixed, steady-state crystallizer.

Book Synopsis Dynamics of Snow and Ice Masses by : Samuel C. Colbeck
Download or read book Dynamics of Snow and Ice Masses written by Samuel C. Colbeck and published by Elsevier. This book was released on 2012-12-02 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamics of Snow and Ice Masses gives an outline of snow and ice studies with an emphasis on essential properties and processes. The monograph also treats the dynamical aspects of snow and ice masses. The text covers topics such as the flow and temperature of ice sheets and shelves, the numerical modeling of ice-sheet changes; the structure of glaciers, the experimental creep behavior of ice, flow law of glacier ice, and advance and retreat of glaciers. Also covered are topics such as sea ice - the physics of its growth, drift, and decay; iceberg deterioration, sources, drift, and drift patterns; and freshwater ice growth, motion, and decay. The book is recommended as a textbook for graduate-level students of snow and ice studies and as reference for climatologists.

Book Synopsis Freezeup Dynamics of a Frazil Ice Screen by : Kathleen D. Axelson
Download or read book Freezeup Dynamics of a Frazil Ice Screen written by Kathleen D. Axelson and published by . This book was released on 1990 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fence booms made of wire mesh screen have been proposed as economical, temporary frazil ice control structures. These screens incorporate frazil ice as it freezes to the screen material, eventually forming a frazil ice dam and raising the water level at a specified location. The purpose of raising the water level is to allow the formation of a stable ice cover that will incorporate still more frazil ice through hydraulic thickening of the cover and deposition beneath the cover. A series of experiments examining the freezeup and blocking dynamics of an expanded metal frazil ice screen were conducted using both an impermeable barrier and frazil ice. A qualitative analysis of the complex frazil ice accumulation process indicated three phases of blocking - an orifice flow stage, a transition stage, and a permeable flow stage. Downstream velocities decreased during the permeable flow stage, although piping resulted in velocity jets. The test results indicate that a rapidly and completely blocked screen is desirable to minimize the time during which high downstream velocities, which lead to bed scour, occur.

Book Synopsis The Drift of Sea Ice by : Matti Leppäranta
Download or read book The Drift of Sea Ice written by Matti Leppäranta and published by Springer Science & Business Media. This book was released on 2011-03-22 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Second Edition of The Drift of Sea Ice presents the fundamental laws of sea ice drift which come from the material properties of sea ice and the basic laws of mechanics. The resulting system of equations is analysed for the general properties of sea ice drift, the free drift model and analytical models for ice drift in the presence of internal friction, and the construction of numerical ice drift models is detailed. This second edition of a much lauded work, unique on this topic in the English language, has been revised, updated and expanded with much new information and outlines recent results, in particular in relation to the climate problem, mathematical modelling and ice engineering applications. The current book presents the theory, observations, mathematical modelling techniques, and applications of sea ice drift science. The theory is presented from the beginning on a graduate student level, so that students and researchers coming from other fields such as physical oceanography, meteorology, physics, engineering, environmental sciences or geography can use the book as a source book or self-study material. First the drift ice material is presented ending with the concept of ‘ice state’ – the relevant properties in sea ice dynamics. Ice kinematics observations are widely presented with the mathematical analysis methods, and thereafter come drift ice rheology – to close the triangle material – kinematics – stress. The momentum equation of sea ice is derived in detail and its general properties are carefully analysed. Then follow two chapters on analytical models: free drift and drift in the presence of internal friction: These are very important tools in understanding the dynamical behaviour of sea ice. The last topical chapter is numerical models, which are the modern tool to solve ice dynamics problem in short term and long term problems. The closing chapter summarises sea ice dynamics applications and the need of sea ice dynamic knowledge and gives some final remarks on the future of this branch of science.

Book excerpt: Frazil ice forms in flowing or turbulent water that has become supercooled by heat transfer to overlying air. This report investigates the influences of turbulence and water temperature on frazil ice formation. The rate and the quantity of frazil ice formed in a specified volume of supercooled water increase with both increasing turbulence intensity and decreasing water temperature. The influence of turbulence intensity on the rate of frazil ice formation, however, is more pronounced for larger initial supercooling. The turbulence characteristics of a flow affect the rate of frazil ice formation by governing the temperature to which the flow can be supercooled, by influencing heat transfer from the frazil ice to surrounding water, and by promoting collision nucleation, particle and floc rupture and increasing the number of nucleation sites. Larger frazil ice particles form in water supercooled to lower temperatures. The particles usually were disks, with diameters several orders greater than their thickness. Particle size generally decreased with increasing turbulence intensity. This report develops an analytical model, in which the rate of frazil ice formation is related to temperature rise of a turbulent volume of water from the release of latent heat of fusion of liquid water to ice. Experiments conducted in a turbulence jar with a heated, vertically oscillating grid served both to guide and too calibrate the mathematical analytic model as well as to afford insights into frazil ice formation. The formation of frazil ice was studied for temperatures of supercooled water ranging from -0.9 deg to -0.05 deg C.
