Conductor icing: Comparison of a glaze icing model with experiments under severe laboratory conditions with moderate wind speed

摘要

The purpose of this paper is to compare the results of a 3D numerical, morphogenetic model of glaze ice accretion on a non-rotating unheated cylinder with experimental data. The numerical method is a stochastic model capable of predicting the mass of ice accretion and its shape as a function of the associated weather conditions. The experimental tests were undertaken in the CIGELE Atmospheric Icing Laboratory at the University of Quebec in Chicoutimi. The influences of air temperature and precipitation rate are investigated. The main goal of this work is to compare the numerical results with laboratory experimental results of severe icing conditions with moderate wind speed. The model is able to predict arrays of icicles, even if they are too long and thin while the total mass is underpredicted. (C) 2015 Elsevier B.V. All rights reserved.
