| 摘 要： | 使用计算流体力学(CFD)技术,结合动网格技术和刚体运动学理论,对室内人体移动进行了动态模拟,得到了人体移动过程中不同时刻室内流场分布.分析了移动过程中的平均温度、平均速度、温度和速度不均匀性指标,并预测了有效吹风温度(TEDT)、空气分布特性指标(ADPI)和吹风感的不满意率指标(PD),比较了不同人体移动速度对以上指标的影响.模拟结果表明,人体移动对室内气流分布和热舒适有短期影响,能提高室内风速的扰动,造成吹风感.

| Abstract: | Simulation of human motion indoors was carried out by using the computational fluid dynamic(CFD) technique with the integration of the dynamic mesh model and the rigid kinematics.The velocity distributions were obtained during the moving process.Meanwhile,the different parameters were compared,including the average temperature,average velocity,kT and kV,the effective draft temperature(TEDT),air distribution performance index(ADPI) and percentage of dissatisfied index(PD) with the consideration of the impact of human motion.The results have shown that human motion has a significant impact on indoor airflow distribution and thermal comfort in a short period of time.This study is helpful to the further investigation of the impact of human motion on indoor environment. |
