摘　　要：针对传统室内空气物理环境监测方式无法充分表征物理场全局分布特性的问题,本研究提出以数值模拟与数据同化为核心的数字孪生技术,通过在虚拟模型中融合观测数据来实现室内空气环境可视化。以博物馆展厅为例展开的应用测试表明,该技术能够结合少量的现场实测数据来求解空间中物理场的分布状态,并且模拟结果较为准确。该技术的应用有助于直观判断室内是否存在空气状态未达标的空间区域,为室内环境控制提供较为完善的信息服务。To address the problem that traditional methods for monitoring the physical environment of indoor air cannot adequately characterise the global distribution of the physical fields,this study proposes a digital twin technique with numerical simulation and data assimilation as the core,which enables the visualisation of the indoor air environment by fusing observed data in a virtual model.Taking the museum exhibition hall as an example,application test shows that the technique can present the distribution of physical fields in space with a small amount of on-site measurement data,and the simulation results are largely accurate.The application of this technology helps to visually judge whether there are spatial areas in the room where the air status is substandard,providing a more complete information service for indoor environmental control.
