Abstract: Abstract: Icing on the airplane is an important factor for the safety of aviation, but the impact of surfaces on icing growth is not fully understood. In this paper, the icing process of the supercooling water on the substrate was studied. The vertical and horizontal growth of ice were recorded respectively by using 2view high speed cameras.The influence of contact angle and thermal conductivity on the ice growth was studied respectively. The influence of contact angle and surface energy on horizontal ice growth was analyzed in detail. The results show that the thermal conductivity can significantly influence the horizontal velocity and shape ofice.The contact angle has little influence on thehorizontal velocity when the thermal conductivity is large,but it has a great influence at a lower thermal conductivity.

Key words: Key words: surface energy, icing on substrate, velocity of icing, contact angle, thermal conductivity
