Imai studies on ice accretion
Witryna1 lip 2010 · Abstract The ability to model and forecast accretion of ice on structures is very important for many industrial sectors. For example, studies conducted by the power transmission industry indicate that the majority of failures are caused by icing on overhead conductors and other components of power networks. This paper presents … WitrynaThis video covers the topic Ice accretion in aircraft frame and engines, which comes under aviation meteorology studies for pilots

The process by which a layer of ice ( icing) builds up on solid objects that are exposed to freezing precipitation or to supercooled fog or cloud droplets. At the earth's surface this usually refers to glaze formation, and the amount of ice can be roughly measured by an ice-accretion indicator. For airborne objects, ice …
Witryna14 kwi 2024 · To address the issues of not accurately identifying ice types and thickness in current fiber-optic ice sensors, in this paper, we design a novel fiber-optic ice sensor based on the reflected light intensity modulation method and total reflection principle. The performance of the fiber-optic ice sensor was simulated by ray tracing. The low … WitrynaThese studies have shown that ice accretion on cables would cause changes in the aerodynamic behaviour of the bridge cables. Several models were developed to determine the ice and snow thickness and the accretion weight [4, 26-30]. One of the . 2 of 8 assumptions used in estimating the profile of the accretion was
