不同的计算机模拟人（CSP）已被开发出来，用于代表室内气流模拟中使用计算流体力学（CFD）的居住者。简单的CSP是首选，以避免非常精细的网格和较长的计算时间。然而，不同复杂度的CSP对CFD模拟精度的影响还没有得到很好的研究。本文旨在定量研究CSP简化后的模拟精度。提出了一种详细的仿人CSP和三种不同的简化策略，包括过度简化的矩形盒CSP、使用多个长方体表示人的不同部位的简单CSP，以及一种改进的CSP，其中不同部位（头部、身体、手臂、腿部）的总热量与详细CSP的总热量相匹配。 将简化的CSP模拟结果与基准实验数据和置换通风情况下的详细CSP模拟结果进行了比较。结果表明，所有CSP，无论是简单的还是复杂的，都为全球现场研究提供了可接受的模拟结果。对于人周围的微环境，采用非常复杂的CSP几何形状似乎也没有显著的好处。相反，应注意确保简化CSP的热源和污染源与实际人体（详细CSP）的一致性。单位:干燥: Ashrae Transactions，第115卷，第1页。2009年1月，芝加哥

Different computer simulated persons (CSPs) have been developed to represent occupants for indoor airflow simulation using computational fluid dynamics (CFD). Simple CSPs are preferred in order to avoid very fine grids and long computing time. However, how CSPs with different complexity affect the accuracy of CFD simulation is not well studied yet. This paper intends to investigate quantitatively the simulation accuracy due to CSP simplification. A detailed, human-like CSP and three different simplification strategies including an overly simplified rectangular box CSP, a simple CSP using several cuboids to represent different parts of a person, and an improved one in which the total heat of different parts (head, body, arms, legs) matches that of the detailed CSP are proposed. The simulation results using simplified CSPs are compared with the benchmark experimental data and simulated results using the detailed CSP in a displacement ventilation case. Results show that all the CSPs, simple or complex, yield acceptable simulation results for the global field study. For the micro-environment around the person, there seems no significant benefit by adopting very complex CSP geometry either. Instead, attention should be paid to ensure the heat and pollutant source consistence of the simplified CSP over the actual human (detailed CSP).Units: SI
