Abstract
The paper presents some brief details of the recent modifications and enhancements made to the ice accretion prediction code CANICE for an improved prediction of ice shapes. The specific areas addressed in this paper include (a) an improved model for roughness prediction, (b) a shear-driven water-runback model, (c) an improved flow field calculation specially in the vicinity of the front stagnation point, (d) an improved model for surface paneling based on a panel length and angle criteria for a consistent and uniform growth of ice, and finally the (e) incorporation of compressibility effects. The effect of each of the above modifications on the resulting ice accretions are illustrated as well as discussed along with comparison with the experiments. The paper concludes, with some recommendations for further improvements in ice accretion prediction.
