Abstract
In this paper, a two-dimensional transmission line icing model is established to predict the ice shape. The air flow field and convection heat transfer were calculated by Fluent software. The discrete phase model (DPM) based on the Lagrangian method was used to calculate the collection coefficient of water droplets on the surface of the transmission line. The Messinger thermodynamic model was solved by user-defined function (UDF) programming of the Fluent, and the ice shape and ice thickness on the surface of the transmission line were calculated. The effects of wind speed, water droplet median volume diameter (MVD), temperature, air moisture content and wind direction angle on the transmission line icing characteristics are considered in the study. The UDF is used to realize the forced vibration of the transmission line. The influence of the vibration of the transmission line on the icing characteristics is emphatically analyzed, and the influence laws of the vibration amplitudes and frequencies on the local water droplet collection coefficient and the icing shape are obtained.
