Numerical Simulation Analysis of Bottom Plate Temperature Based on Meteorological Data and Different Working Conditions

通过8个不同厚度底板的测温试验,对地下室内小环境温度和外界大环境温度的关系进行研究,并给出不同工况下地下室内小环境温差取值系数。提出基于当地气象数据与不同工况的底板温度数值模拟分析方法,即依据平均气象温度、不同工况及小环境与大环境温差比值,计算小环境平均温度,以此进行底板温度数值模拟分析,得到底板温度曲线。

Through the temperature measurement tests of 8 bottom plates with different thickness,the relationship between the small environment temperature in the basement and the large environment temperature outside is studied,and the value coefficient of the small environment temperature difference in the basement under different working conditions is given.A numerical simulation analysis method of bottom plate temperature based on local meteorological data and different working conditions is proposed,the average temperature of small environment is calculated according to the average meteorological temperature,different working conditions and the ratio of temperature difference between small environment and large environment,so as to carry out the numerical simulation analysis of bottom plate temperature and obtain the bottom plate temperature curves.
