利用Airpak模拟室内气流组织的误差分析

Error analysis of simulation of indoor airflow organizations with Airpak

利用CFD模拟软件Airpak对某办公室室内气流组织速度场,温度场进行模拟数值计算,并用实测数据与模拟结果进行对比,得到实测数据与模拟结果不符合的结果.对比表明,数值模拟由于边界条件、参数设置,模型选择和操作者理论经验上存在的问题,使得模拟结果与实测数据误差较大;同时实测方法与外界环境的变化也会影响实测数据质量.

An office＇s indoor air velocity and temperature fields are simulated by CFD simulation software. By comparing the measured data with the simulation,the results are not in line. The comparison shows that due to the problems on the boundary conditions, parameter setting, model selection, and operator＇s theoretical experience, simulation has an error from measured data and the measuring methods and change of the external environment can also affect the data quality measured.
