当室内环境采用计算流体力学建模时，通常使用计算机模拟人。计算机模拟的人在大小、形状和几何复杂程度上各不相同，从简单的箱形或圆筒形热源到更人性化的模型。然而，很少有人关注几何体的影响。这项工作提供了一个关于局部和全局气流分布的几何不同的计算机模拟人的调查。结果表明，当考虑通风室的整体气流时，一个简单的几何结构是足够的，因为在距离计算机模拟人一定距离处，几何结构的影响很小或没有。 然而，对于局部流动条件，应采用更详细的几何结构，以评估热舒适性和大气舒适性。单位:SICitation:研讨会，ASHRAE交易，第108卷，第页。2.

Computer simulated persons are often applied when the indoor environment is modeled by computational fluid dynamics. The computer simulated persons differ in size, shape, and level of geometrical complexity, ranging from simple box or cylinder shaped heat sources to more humanlike models. Little effort, however, has been focused on the influence of the geometry. This work provides an investigation of geometrically different computer simulated persons with respect to both local and global airflow distribution.The results show that a simple geometry is sufficient when the global airflow of ventilated enclosure is considered, as little or no influence of geometry was observed at some distance from the computer simulated person. For local flow conditions, though, a more detailed geometry should be applied in order to assess thermal and atmospheric comfort.Units: SI
