提出一种新的CFD热边界条件给定方式,可将室内热源和室外气象信息同时考虑在计算域内。并运用该种热边界条件给定方法针对一个包含外墙和外窗的办公室算例进行模拟,计算结果表明,外墙和外窗内壁面的温度和热流密度分布很不均匀,采用传统的热边界条件给定方式无法给定,但通过本文提出的方法却可容易地获得准确的外墙、外窗内壁面温度和热流密度分布及室内环境温度场等信息,便于研究与设计人员使用,具有一定的工程实用价值。
In this paper, a new method of thermal boundary conditions for CFD is proposed, which can consider indoor heat source and outdoor weather information in the calculation domain simultaneously. The thermal boundary conditions given method is used to simulate an office example with exterior wall and exterior window. The results show that the temperature distribution and the heat flux density in the inner wall of the outer wall and the outer window are uneven. The traditional heat However, the method proposed in this paper can easily obtain the accurate information of wall temperature, heat flux density and indoor ambient temperature field in the external wall and outer window, which is convenient for the researchers and designers to use Certain engineering value.
