温湿度场仿真模拟在博物馆环境监测中的应用研究

Research on the application of temperature and humidity field simulation to environmental monitoring in museums

针对博物馆当前的环境监测方式无法全面感知温湿度空间分布的问题,本研究引入与数据同化(EnKF)算法相结合的计算流体动力学(CFD)模拟方法,以某博物馆的展厅空间为例,获得可视化的温湿度场仿真模拟结果,并结合藏品保护要求进行数据分析和相关讨论。经与实时监测数据对比,基于数据同化的CFD模拟准确性良好,误差在可接受范围内。本研究引入的技术方法实现了博物馆环境监测从“点监测”到“场监测”的转变,后续可为博物馆藏品预防性保护提供更加科学有效的技术支撑。

With the goal of solving the problem that the current environmental monitoring method cannot fully perceive the distribution of temperature and humidity in museum building spaces,this study introduces the computational fluid dynamics(CFD)simulation method,which can be combined with the data assimilation(EnKF)algorithm.Taking the exhibition hall space of a museum as an example,we obtained the visual simulation results of temperature and humidity fields and carried out the data analysis and related discussion according to the requirements of collection conservation.Compared with the real monitoring data,the CFD simulation based on data assimilation had good accuracy and the error was within an acceptable range.The technological method introduced in this study has realized the transformation from“point monitoring”to“field monitoring”for museum environmental monitoring.This could provide a more scientific and effective technological support for the preventive conservation of museum collections.
