A systematic study has been made of the adhesion of glaze and rime on an aluminium conductor as a function of the roughness of the conductor, the velocity of the air flow containing supercooled droplets and the ambient temperature. Supercooled droplets of 20 μm mean diameter were accumulated on an aluminium conductor placed in the 23-cm x 23-cm working section of an open wind tunnel. Adhesion tests were made on a 3-cm-length sample, taken from the central part of the ice accretion. Density measurements and microstructural observations were also made. It is shown that the adhesion strength depends on the roughness of the conductors, the ambient temperature and the velocity of the wind.
