基于FLOTRAN CFD分析的房屋表面风压分布研究

Study on wind pressure distribution on the surface of houses based on FLOTRAN CFD analysis

采用RNGk-湍流模型,使用FLOTRANCFD对12种不同坡度的单层双坡房屋在3种不同风向角的风作用下的墙体表面风压进行数值模拟,得到了房屋墙体表面的风压分布规律,危险区域位置,以及坡度变化对房屋表面风压分布的影响.

This paper adopted RNG k-turbulence model and used FLOTRAN CFD to simulate wind pressure distribution on the surface of single-layer double-slope-roof buildings with 12 kind of roof-angles.These buildings suffer from 3 different wind directions.The rule of wind pressure distribution,the location of dangerous areas,and the influence on wind pressure distributions from gradient change have been gained.
