摘　　要：以某美术馆D展厅为研究对象,采用计算流体力学的方法对大空间建筑室内气流组织分布进行模拟,CFD的模拟计算采用基于有限容积法的软件Phoenics来完成,模型为高雷诺数的k-ε两方程紊流模型,采用SIMPLE算法.在离散过程中,采用交叉网格.通过CFD模拟值与现场实测值进行比较,考察模拟值与实测值趋于一致的程度,并分析室内气流温度场和速度场的分布特点.对空调系统节能和大空间建筑设计优化有一定指导意义.Computational Fluid Dynamics （CFD） method was adopted in this paper to simulate the distribution of indoor airflow in large space building in an art gallery D hall. The CFD calculation is carried out by finite volume code Phoenics . The flow is described by high Re k-ε two-equation turbulent model, and SIMPLE algorithm is applied. In the discretion process, staggered grid was adopted. Through comparison bewteeen the CFD prediction and the experimental data, it testified the degree that simulation results agreed reasonably with experimental data and analyzed the distribution characteristics of indoor airflow temperature and velocity field. It＇s important to guide energy saving on air conditioning system and optimization design in large space building.
