Book Description
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).

Book Description
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).

Book Description
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.
