连通类高大空间气流组织数值模拟研究

Simulation of Air Distribution in Run-through Large Space

本文将CFD技术应用到对科技馆建筑气流组织设计优化中,解决实际工程中遇到的连通类高大空间的问题,并对CFD技术在暖通空调领域设计环节的应用进行了一定的探索。针对实际科技馆气流组织设计的特点,使用商业软件Fluent,在简化模型的基础上,采用标准k-ε模型,分析连通类高大空间建筑的空气流动现象以及空间内的温度场、速度场分布等,为进一步的科学研究和工程设计提供指导。

Run-through large space is a new kind of architectural form. Function and trait of this architecture have great difference with ordinary large space. It needs study deeply air distribution of this special large space. On the base of the model in this article, the airflow, temperature field and velocity field in the run-through large space were simulated adopting standard κ-ε model with commercial software Fluent. CFD technology is applied to optimize the air distribution in this paper, which will solve the difficult problems existing in run-through large space.
