Abstract
The principle of numerical computation of wind pressure on parabolic antenna ts discussed in this paper. The numerical simulation of wind pressure on the surface of parabolic antenna was performed base on Reynolds-averaged N-S equations and K-Omiga turbulent model. The wind pressure and wind speed distribution on the antenna surface were obtained. The characteristics of wind pressure and speed distribution on the front and back of the antenna are analyzed. On the basis of the analysis, the numerical compulation results of laminar flow, K_Epsilon, RNK_Epsilon and LES turbulent simulation models was calculated. The effect of different turbulent models on wind load is analyzed. The relation of wind speed, wind load and wind load coefficient are elaborated.关键词
