覆冰导线临界融冰电流数值模拟分析
Numerical Simulation Analysis on Critical Deicing Current of Iced Conductor
摘要
Abstract
A numerical simulation method based on ANSYS-FLUENT software was used to calculate critical deicing current and influence of environmental conditions, icing layer types and ice thickness was discussed. Shear stress transport (SST) model in the k-omega turbulence model was adopted to analyze flow field around the icing conductor by simulation. Result indicates the environmental temperature is higher, critical deicing current is smaller. And, the environmental air velocity is higher, critical deicing current is larger. In addition, heat conductivity coefficient of the icing layer is large, critical deicing current is larger. When ice thickness is less than 25 mm, ice is thicker, critical deicing current is larger. The error between simulation result and experimental result is less than 10% , which proves that this numerical simulation method can predict critical deicing current value.关键词
