摘要
基于CFD方法分析了人体移动过程对某学生工作室内部环境热舒适性的影响。建立该学生工作时的全尺寸几何模型,并采用动网格方法模拟人体移动时引起的非稳态流动,求解三维非稳态雷诺时均N-S方程来获得室内的气流流动特性。结果表明,人体移动会对室内的温度场与速度场造成不同程度的影响,同时人体的移动速度大小与人体移动的方向都能够对室内热环境产生影响,分析结果可以为评估在大规模人员流动下的火车站或者大型商场的热舒适性提供一定的参考。
The effect of human body movement process on the indoor environment thermal comfort in a students＇ working studio was analyzed using CFD method. A full-scale geometry model was built to simulate the unsteady flow caused by the movement of the human body through the dynamic mesh method. Airflow characteristics of student＇ studio was obtained by solving 3D Reynolds-average Navier-Stokes Equations. The results showed that the human body movement can cause varying degrees of impact on the temperature field and the velocity field, moreover, the velocity magnitude and direction of human body movement also have impacts on the indoor thermal environment, which providing a reference method to make a assess about the thermal comfort in the railway station or shopping mall.
