摘要:
办公建筑室内污染物扩散浓度的分布会受到气流组织变化的影响,由于气流组织的不同污染物扩散程度及分布也不同.传统方法利用一些实验仪器测量或利用数学模型来推测污染物扩散分布规律,但忽略了空气对流对扩散的影响且实验过程比较繁琐,无法准确地推测室内污染物扩散的分布规律.本文采用FLUENT软件对严寒地区办公建筑污染物在不同风压下扩散分布规律进行模拟分析.模拟过程通过Gambit软件建立计算模型及边界条件的定义,利用FLUENT软件对污染源组分的传输进行计算,求解及后处理得到最优解,从而为建筑通风设计的合理化提供理论依据.
Abstract:
The distribution of indoor pollutant concentration in office buildings is affected by changes in airflow organization,and the degree and distribution of different pollutants in the airflow organization are also different.The traditional method is to use some experimental instruments to measure or use mathematical models to speculate the distribution of pollutants.These methods ignore the influence of air convection on the diffusion and the experimental process is cumbersome,and it is impossible to accurately predict the distribution of pollutants in the room.In this paper,FLUENT software is used to simulate the distribution of pollutants in office buildings in severe cold regions under different wind pressures.The simulation process establishes the definition of the calculation model and boundary conditions through Gambit software,and uses FLUENT software to calculate the transmission of the pollution source components,and solve and post-process the optimal solution,thus providing a theoretical basis for the rationalization of building ventilation design.
