Download or read book Climatic Chamber Tests of a Surface Ice Accretion Measurement System written by Paul Tattelman and published by . This book was released on 1979 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climatic chamber tests of an off-the-shelf ice detection system manufactured by Rosemount Engineering Company were conducted to evaluate its capability to determine ice amounts measured on cylinders. One-hour tests were run for a variety of windspeeds, temperatures, and icing conditions. Some longer duration tests, up to 17 hours, were also performed. Analysis of the data indicates that the Rosemount system is highly correlated with the mass of ice measured on the cylinders when the data are divided into freezing rain and rime icing events. The Rosemount system is also highly correlated with ice thickness, but without the pronounced dependence upon the type of icing. In the light of positive test results, a method is proposed for utilizing the Rosemount system for observing ice accretion at the earth's surface. (Author).

Download or read book Field Tests of a Surface Ice Accretion Measurement System written by Paul Tattelman and published by . This book was released on 1980 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rosemont ice detectors were installed at four New England locations to collect information on their response to icing near the earth's surface. Data were collected for 11 icing events during the 1979-80 winter season. These included, for each icing event, the recorded output o the ice detectors, the mass, thickness and physical properties o the ice on a control cylinder, and meteorological conditions pertinent to the field tests. The data were analyzed to determine how accurately ice amounts on the cylinder could be estimated from the output of the ice detectors. Results indicate that the detector would be excellent for objectively estimating icing amounts on a cylinder for in-cloud icing on mountaintops. A slight modification and further testing is necessary to best use the instrument to estimate icing amounts from freezing rain or drizzle. A method for making standardized observations of the mass and thickness of ice on cylinders with varying diameters is also presented. (Author).

Download or read book Contamination Mitigating Polymeric Coatings for Extreme Environments written by Christopher J. Wohl and published by Springer Nature. This book was released on 2020-05-15 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides perspectives on the approaches, mechanisms, test methods, durability considerations, and environmental concerns for contamination mitigating coatings and polymers with emphasis on their use in more extreme aerospace and marine terrestrial environments. Parts of the Volume are devoted to application of biomimetics to contamination mitigation polymeric coatings, low ice adhesion surfaces, insect residue adhesion resistance coatings, and marine biofouling mitigation materials. By juxtaposing ice insect, and marine mitigation approaches, researchers and users may more easily identify threads of similarity that will assist in future developments and potential applications in these areas. The volume is of interest to chemists and material scientists in providing awareness of both the need for efficacy in mitigating contamination and for appropriate coating durability; to physicists in providing better understanding of the interaction between the contaminant, the coated surface, and the surrounding environment; and to engineers in describing the need for better scale-up tests between laboratory and field environments.

Book excerpt: This report contains 56 conference papers pertaining to snow removal and ice control research including Canadian research and equipment. Several of the papers are concerned with deicing salts--their effectiveness, their impact on the environment, and possible alternatives to them. Alternative methods of deicing discussed herein include: heating of bridge decks, increasing coefficient of friction between tires and pavement surfaces, use of high intensity lights, and advent of less corrosive chemicals. There are also several papers that address the problem of snow and ice accretion on power wires, guideway systems, sign boards, and etc. There is considerable attention given to development of computer programs and models for predicting scope of snow and ice control operations and for evaluating their effectiveness. Also, several papers discuss new developments in snow removal equipment and the cost of operation and maintenance.
