✦ Synopsis


Phase change heat transfer with incoming supercooled droplets on heated curved surfaces is examined. The processes of rime ice, transition and combined rime/glaze ice conditions are modelled. In the analysis, heat conduction equations in the ice and unfrozen water layers are solved simultaneously with the mass balance, including incoming droplets. Energy input from the heated boundary (due to electrical heat generation) affects the growth of the glaze film thickness and associated liquid runback along the ice surface. Validation of the predictive model is carried out through comparisons with experimental data [Lu et al., A semi-empirical icing model for an energized power line, Internal Report,
