高大空间分层空调室内气流的数值模拟

Numerical Simulation Of Air-Distribution In A Delaminated Air-Conditioned Large Spaces

分层空调是高大空间建筑典型的气流组织方式。本文利用计算流体力学(即CFD)方法对一个典型装有分层空调的高大厂房房间内的三维气流进行了数值模拟。其中,使用标准k -ε模型, 运用SIMPLE 算法进行离散。预测了房间内的速度场、温度场,表明CFD 模拟可以为分层空调系统的节能和设计提供依据。

The delaminated air-conditioning is a typical airflow in a large space. 3D airflow in a typical delaminated air-conditioned large space was numerical simulated using CFD. The standard k ? turbulence model was used to solve ε equations. The SIMPLE scheme is used here for numerical discretization. It is predicted the velocity field temperature field. The result showed that CFD simulation can provide a basis for the energy saving and design of delaminated air-conditioning.
