摘　　要：为了提升口腔医院建筑诊疗空间的疫情防控能力,对病患人员口腔中喷溅的气溶胶颗粒进行四种工况的CFD模拟分析,获得气溶胶颗粒在自然状态、口外负压作用、空调作用以及口外负压与空调共同作用下的运动规律,为优化设计三级医疗流程、诊疗空间布局和空调通风系统提供数值分析参考。In order to improve the epidemic prevention and control ability diagnosis and treatment space in stomatological hospital buildings,the aerosol particles splashed in the patient's mouth were analyzed by CFD simulation under four working conditions,and the movement rules of the aerosol particles under the natural state,the role of extraoral negative pressure,the role of air conditioning,and the combined role of extraoral negative pressure and air conditioning were obtained,providing a numerical analysis reference for optimizing the design of the three-level medical process,the layout of diagnosis and treatment space,and the air conditioning and ventilation system.
