A novel model for glaze ice accretion
(2023) In Technische Mechanik 43(1). p.178-188- Abstract
This paper introduces a novel model to predict ice accretion in glaze ice conditions due to supercooled water droplets. Glaze icing is controlled by a large number of interacting physical phenomena. The purpose of the suggested model was to offer a faster alternative to explicitly modelling these phenomena. The paper presents the suggested model and investigates the sensitivity of the predictions on the model parameters for three experimental cases in the literature. The results indicate a qualitatively correct behavior. Quantitatively, the model over-predicts the amount of accreted ice, the error being significantly larger in severe icing conditions. The errors are caused partly by the choice of faster numerical approaches and by the... (More)

The results indicate a qualitatively correct behavior. Quantitatively, the model over-predicts the amount of accreted ice, the error being significantly larger in severe icing conditions. The errors are caused partly by the choice of faster numerical approaches and by the lack of possibility to account for detaching ice from the surface.
