Property-variable rime iceAircraft icingHeat transferA new one-dimensional model has been developed to describe the aircraft icing process based on the fundamental theory of solid鈥搇iquid phase change. The model assumes that there exist two modes for aircraft icing, i.e. the dry and the wet ...

Predicting glaze or rime ice growth on airfoils A droplet trajectory analysis model is combined with calculations of heat transfer to provide predictions of glaze or rime ice during flight. Such a predic... Politovich,K Marcia - 《Journal of Aircraft》 被引量: 182发表: 2000年 Numerical ...
The main objective of this paper is to model the rime-ice accretion process on a horizontal-axis wind turbine (HAWT) operating under icing conditions. The model calculation procedure was divided into two stages. The first stage consists of computing the two-phase flow that is composed of air ...
A cooler () may cool the surface () for anticipating the formation of ice with a heating process. The invention can be used for detecting rime and/or rime conditions on a flying aircraft.doi:US8485473 B2Nicolas PiccoBruno ThillaysPhilippe Portier...
and demonstrated in the laboratory that it is scientifically possible to independently and simultaneously sense liquid (unfrozen) and ice (frozen) water and rime ice accumulations on the leading edges of an aircraft or helicopter rotor blade in real time with a lightweight solid-state electronic ...
Rime, white, opaque, granular deposit of ice crystals formed on objects that are at a temperature below the freezing point. Rime occurs when supercooled water droplets (at a temperature lower than 0° C [32° F]) in fog come in contact with a surface tha

In 1954, model testing in an icing wind tunnel was carried out by Hugger and Englar, and some characteristics of ice were found [19]. In 1967, Jackson conducted a development study on scale models in an icing tunnel to determine the ice caught on a prototype aircraft with particular ...
