DC Ice-Melting Model for Elliptic Glaze Iced Conductor

Abstract

Both practices and experiments show that the cross-section shape of iced conductor has an obvious influence on ice-melting time, but it is ignored by almost all existing ice-melting models which assume that the iced conductor has a perfect circular cross-section shape. Based on the observed results in the natural icing station, this paper has analyzed the shape characteristic of the iced conductor, and described the cross-section shape of iced conductor with an ellipse, then put forward a model to simulate the ice-melting process on an iced conductor with an elliptic cross-section. The simulated results have been validated in the natural icing station. The results of experiments and simulations show that the ice-melting time of the elliptic iced conductor is less than that of the circular iced conductor.
