冬奥集装箱房室内热环境多物理场耦合模拟及分析
Simulation and analysis of multi-physical field coupling of thermal environment in Olympic Winter Games container rooms
摘要：
为了研究集装箱房在冬季奥林匹克运动会期间的室内热环境，对集装箱房室内外环境进行了多物理场耦合求解，建立了室外环境、围护结构和室内环境三者的热网模型，对导热、对流、辐射3种传热方式进行了耦合计算。将模拟结果与实际测量数据进行对比分析，验证了该模拟方法的准确性。而后研究了在冬奥会赛事期间，集装箱房采用不同热工性能围护结构时的室内热环境。模拟计算了采用6种不同种类的保温材料及不同厚度的岩棉时，室内温度的变化情况。结果表明：综合经济性和保温材料特性，选择岩棉较为合适，且当其厚度为150 mm时，室内温度约为19.6 ℃，满足冬季室内温度的要求。
Abstract：
In order to study the indoor thermal environment of the container room during the Olympic Winter Games, this paper couples the multi-physical field solution for the container rooms and the indoor and outdoor environment, establishes the heat network model of the outdoor environment, the envelope and the indoor environment with coupling the three heat transfer modes of heat conductivity, convection and radiation. The accuracy of the simulation method is verified by comparing and analysing the simulation results with the experimental data. Then, this paper studies the indoor thermal environment of the container rooms with different thermal performance envelopes during the Olympic Winter Games events. The simulation calculates the indoor temperature of 6 different kinds of insulation materials and different thicknesses of rock wool. The results show that the choice of rock wool is more appropriate while combining economy and thermal insulation material characteristics. And when its thickness is 150 mm, the indoor temperature is about 19.6 ℃, meeting the requirements of indoor temperature in winter.
