Abstract: A new time-dependent icing model, which extends that of Lozowski, Stallabrass and Hearty and determines the shape and total ice accretion Mass, has been developed. A cylinder with accreted ice is divided into twenty-four sectors. The equation of non-stationary heat balance is written for each sector. The resulting set of differential equations is solved numerically. Using the proposed model, it has been possible to examine the influence of cylinder material and initial cylinder temperature on the ice accretion. Calculations have also been made for hollow cylinders with different internal conditions. The significance of water droplet temperature has also been examined. The time-dependence of the model provides information about the effects of changing each icing parameter during the simulation. The model predicts ice shape with some accuracy for both dry and wet conditions.
