中文摘要：

对环境模拟实验室空间场的温度和速度进行了多工况数值模拟．考虑环境模拟实验室的特点，着重研究了模拟器高度为2rn，A组灯打开情况下不同送风时的温度和速度场情况，并将数值结果与实验结果进行了对比分析．结果表明：速度模拟相对温度模拟要精确，其模拟值与实验值基本一致，温度场实验值较模拟值偏高，但总体误差不超过0．3℃，按模型验证量化指标中的均方根差（RMSE）对各物理参数各工况下的结果进行评价，得出：高度为0．2m、0．6m、1．0m、1．5m时温度RMSE分别为5．3％、7．1Vo、6．5％、8．9％，对应高度的速度RMSE分别为2．1％、3．4％、4．1％、5．3％．整个模拟的平均均方根差为5．34％，该数值模型可作为其他工况的基准模型．

英文摘要：

Numerical simulations of temperature and velocity field of the environment simulation laboratory space under multiple conditions were carried out. Considering the characteristics of the environment simulation laboratory, with Group A lamp of the simulator on at the height of 2 m, numerical results were compared with the experimental results. The re- sults showed that： the simulation results of temperature are more accurate than that of wind velocity and both simulation values are respectively consistent with the experimental ones. The experimental temperature value is no more than the simulation one by 0. 3 C. According to the model validation root mean square error （RMSE）, the following results could beachicved： at the height of 0.2 m, 0.6 m, 1.0 m, 1.5 m, the air temperature RMSE are 5.3 %, 7.1 %, 6.5 %, 8. 9 %, corresponding to the high wind velocity RMSE of 2.1 %, 3.4 0%, 4.1 %, 5.3 %. The average root mean square error of the simulation was 5.34 %, and the numerical model can be used as the baseline model for other working condi- tions.
