置换通风空调房间气流组织的数值模拟

摘要

以工程中广泛采用的K-ε二方程湍流模式为基础，运用计算流体力学的有限差分法对两种置换通风空调房间的三维速度场、温度场和污染物的浓度场进行数值模拟，体现这种新型空调送风方式的特点和优点，并为置换通风房间的设计和研究提供一定的理论依据。%On the basis of the K－ε turbulent flow model,The article simulated the three-dimensional flow field,the temperature field and the contamination field of the air conditioning rooms with displacement ventilation.This study was wished to show the specialty and merit of this kind of air conditioning and provide gome f scietific basis for designing and researching the air conditioning rooms with displacement ventilation.
