Download or read book Proceedings of First International Workshop, Atmospheric Icing of Structures written by L. David Minsk and published by . This book was released on 1983 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: The accumulation of ice in its various forms on structures has long been recognized as a significant and costly problem for both industry and government world-wide. The purpose of this First International Workshop on Atmospheric Icing of Structures was to bring together scientists, engineers and managers from industrial and military organizations from around the world that have an interest in the accretion of ice on structures. The presumption underlying the use of 'First' in the title of the workshop is that this meeting would demonstrate the need for continued exchange of ideas, of reports of work accomplished and of future plans, and further identification of research areas requiring particular attention. The 39 papers from 10 countries presented at the workshop were organized into four technical sessions representing the various aspects of structural ice accretion studies underway. Topics included: Basic research; Physics of ice accretion; Simulation and modeling; Design-oriented research; Meteorological measurements and damage observations; and Iceload measurements and design practices.

Book Synopsis Experimental and Numerical Modeling of Wet Snow Accretion on Structures by : Alessandro Vigano
Download or read book Experimental and Numerical Modeling of Wet Snow Accretion on Structures written by Alessandro Vigano and published by . This book was released on 2012 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present work aims at studying the atmospheric phenomenon of wet-snow accretion to structures. This phenomenon may induce severe damages to structures. Freezing particles which generate wet-snow accretions are characterized by a mixed phase ice/water. The particle state in this framework is quantified by a dimensionless parameter: the liquid water content LWC defined as the ratio of the particle liquid mass to the whole particle mass. This LWC definition is different form the aeronautical one. In this work, wet snow is produced with an ambient temperature below 0°C. Both experimental and numerical approaches are undertaken to investigate the subject. The experimental approach, undertaken in a climatic wind tunnel, is based on the LWC effect on the accretions obtained on a test structure. The particle LWC is tuned by adjusting the ambient temperature of the test chamber. The results are synthesized by a coefficient [beta] defined as the ratio of the accretion mass flux to the snow mass flux. A first numerical model assesses the boundary conditions of the accretion model, i.e. the particle size distribution upstream the structure and the associated LWC. The first part of accretion model concerns the study of the particle behavior close to the structure which is quantified with a Stokes number. The efficiency of particles to impact the structure is synthesized by a dimensionless parameter n1. The analysis of the experimental coefficient [beta] according to n1 is developed. This allows to study the efficiency of particles to stick on the structure as a function of the LWC. The result is synthesized by the n2 coefficient. The second part concerns an attempt to model the accretion shape by the sticking efficiency n2 as a function of the particle-surface angle of impact. A series of perspectives are presented.

Download or read book Ice Adhesion written by K. L. Mittal and published by John Wiley & Sons. This book was released on 2020-12-15 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book presents ways to mitigate the disastrous effects of snow/ice accumulation and discusses the mechanisms of new coatings deicing technologies. The strategies currently used to combat ice accumulation problems involve chemical, mechanical or electrical approaches. These are expensive and labor intensive, and the use of chemicals raises serious environmental concerns. The availability of truly icephobic surfaces or coatings will be a big boon in preventing the devastating effects of ice accumulation. Currently, there is tremendous interest in harnessing nanotechnology in rendering surfaces icephobic or in devising icephobic surface materials and coatings, and all signals indicate that such interest will continue unabated in the future. As the key issue regarding icephobic materials or coatings is their durability, much effort is being spent in developing surface materials or coatings which can be effective over a long period. With the tremendous activity in this arena, there is strong hope that in the not too distant future, durable surface materials or coatings will come to fruition. This book contains 20 chapters by subject matter experts and is divided into three parts— Part 1: Fundamentals of Ice Formation and Characterization; Part 2: Ice Adhesion and Its Measurement; and Part 3: Methods to Mitigate Ice Adhesion. The topics covered include: factors influencing the formation, adhesion and friction of ice; ice nucleation on solid surfaces; physics of ice nucleation and growth on a surface; condensation frosting; defrosting properties of structured surfaces; relationship between surface free energy and ice adhesion to surfaces; metrology of ice adhesion; test methods for quantifying ice adhesion strength to surfaces; interlaboratory studies of ice adhesion strength; mechanisms of surface icing and deicing technologies; icephobicities of superhydrophobic surfaces; anti-icing using microstructured surfaces; icephobic surfaces: features and challenges; bio-inspired anti-icing surface materials; durability of anti-icing coatings; durability of icephobic coatings; bio-inspired icephobic coatings; protection from ice accretion on aircraft; and numerical modeling and its application to inflight icing.

Download or read book The Density and Structure of Ice Formed by Accretion written by W. C. Macklin and published by . This book was released on 1960 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were made of ice formed by accretion over a wide range of controlled conditions to ascertain the influence of the wind speed, ambient temperature, droplet diameter and liquid water concentration in the supercooled cloud, and the siz of the accreting object. It is shown that these parameters determine the time of freezing and impact momentum of the supercooled droplets, and thereby also the density and structure of the deposits. Application is made to the growth of hail. (Author).

Book Synopsis Techniques for Protecting Overhead Lines in Winter Conditions by : Masoud Farzaneh
Download or read book Techniques for Protecting Overhead Lines in Winter Conditions written by Masoud Farzaneh and published by Springer Nature. This book was released on 2022-02-10 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive review of the various options for improving the performance of overhead power lines in winter conditions, taking into account both mechanical and electrical aspects. Experience within the CIGRE community reveals many strategies to protect overhead power lines from damage caused by heavy build-up of ice and snow or electrical issues such as insulator icing flashovers. The initial approach is to consider the predicted ice loads from the available databases. This is supplemented with some fundamental aspects of icing physics that affect accretion rate as well as factors in ice shedding on traditional (metal, ceramic) and novel treated surfaces. These ice physics concepts structure the ways to categorize and evaluate methods to reduce or prevent icing on conductors and ground wires or to prevent flashover of insulators. Many utilities in cold climate regions have developed and used methods and strategies to reduce ice loads using anti-icing (AI) and / or de-icing (DI) methods. In general, AI methods are used before or early during ice build-up, while DI methods are activated during and sometimes after ice build-up. The book describes and discusses some historical, operational, or potential AI / DI systems in the ice physics context. This supports a comprehensive review of AI coatings including concepts, relevant material properties, application methods, and finally test methods for characterizing the long-term performance.
Book Synopsis Assessment of Ice Accretion on Offshore Structures by : L. David Minsk
Download or read book Assessment of Ice Accretion on Offshore Structures written by L. David Minsk and published by . This book was released on 1984 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The literature on sea spray (superstructure) icing is almost entirely based on observations on moving ships. However, icing on stationary offshore platforms with their fixed vertical columns will differ significantly from ship icing, which is influenced by ship movement and wind and wave directions. An observation program on offshore drilling vessels is proposed, using 1-in.-diam x 8-in.-long cylinders in arrays as a standard measuring technique for spray icing. Atmospheric icing may be a source of ice accretion on derricks in some locations, and the best commercial device currently available for measuring it is the Rosemount detector. Improved devices for both spray and atmospheric ice accretion measurements should be developed. Icephobic coatings have the potential for reducing ice accretion, and testing of candidate materials should be undertaken. Well-documented icing reports by all types of ships or platforms should be made and collected at a central clearinghouse.
