Numerical Simulation of the Local Collection Efficiency on Icing Conductor

The effectiveness of collecting water droplets strongly influences the status of icing on conductors. This work presents an Eulerian approach to calculate the local collection efficiency on two dimensional conductors by the CFD software FLUENT6.2. The simulation results show that: the local collection coefficient is affected by the wind velocity and the median volume diameter (MVD). Comparison between the simulation results and the experimental data in the literature show that the model can be used to accurately calculate the local collection coefficient on icing conductor surface.
