敦煌莫高窟微环境控制系统的CFD仿真及设计

摘要

Aiming at solving the problem of micro environmental variation inside the cave of Mogao Grottoes include temperature, humidity and the concentration of carbon dioxide has signiifcant inlfuence to the preservation of cultural relics consist of murals, statues and so on.Take the measure of CFD to study the change rule of temperature and humidity, carbon dioxide inorder to design a micro environment control systemmake to keep the temperature, the humidity inside the cave remain constant and reduce the concentration of carbon dioxide. The result of experiment shows that the micro environment control system has a certain effect on regulating the micro environmental temperature, humidity and the concentration of carbon dioxide.%针对敦煌莫高窟洞窟内微环境的改变特别是温度、湿度以及二氧化碳浓度的变化对洞窟内的壁画、佛像等珍贵文化遗产的保存具有重大影响的问题，采用CFD仿真技术对敦煌莫高窟进行建模仿真，研究其中温湿度、二氧化碳变化规律，进一步设计一套微环境控制系统使洞窟内的温度、湿度保持恒定以及降低二氧化碳的浓度。实验结果表明设计的微环境控制系统对于调节微环境的温度、湿度以及二氧化碳的浓度具有一定的效果。
