Simulation of icicle growth using a three-dimensional random walk model

Conductor icing: Comparison of a glaze icing model with experiments under severe laboratory conditions with moderate wind speed

“…When it is equal to zero (the effect of the surface tension is turned off); an unrealistic, porous ice accretion is obtained (Szilder et al, 1999). When it is equal to one, a compact ice accretion is obtained (Szilder and Lozowski, 1995;Szilder et al, 1999). For values greater than two, the ice accretion surface is smooth (Szilder and Lozowski, 1995).…”

“…When it is equal to one, a compact ice accretion is obtained (Szilder and Lozowski, 1995;Szilder et al, 1999). For values greater than two, the ice accretion surface is smooth (Szilder and Lozowski, 1995). Therefore the range parameter was set to two in order to yield a reasonable porosity for the accretion (Szilder and Lozowski, 1995).…”

“…The random walk model builds up an ice accretion structure using discrete elements or particles. By developing this new approach, Szilder carried out a two-dimensional [56] and three-dimensional [59] analysis of the ice accretion on a cylinder. These models are a combination of a ballistic trajectory and a random walk model.…”

Experimental and theoretical verification of two icing codes =

“…parameter as the ratio of the probability of moving downward to the probability of motion in any other direction. Based on the previous numerical experiments carried out by Szilder and Lozowski (1995), the value of the motion parameter was chosen as 3.…”
