Abstract

Icing collision coefficient is a key parameter for predicting the growth of conductor icing. Based on the standard turbulence model of gas liquid two phase flow and Euler Lagrange principle

the mathematical model of the two dimensional flow field is established

and the collision coefficient of three typical conductor icing is calculated.The airfoil ice and ellipse ice collision coefficients at different attack angles are calculated. The simulation result shows that the collision coefficient of circular cross section ice is 4.79%

.21% more than elliptical ice with a axial ratio of 4:3 and 4.04%

.14% more than wing shape ice under the same weather conditions. The shape of the ice cover in the same wire is in the range of 0°

0°

the higher the attack angle

the higher the impact coefficient is.
