摘要

摘要对便携式空气净化装置内部气流进行了数值模拟。简化的系统几何结构由关键部件组成——风扇、粒子过滤器和用于消毒的紫外线灯，这些都包含在模型中。研究了空气消毒的速度分布、紫外线辐照度及其对空气消毒的影响。考察了流量和紫外线剂量对纯化效果的影响。这些发现为优化空气净化装置的设计和配置以及它们在减少空气传播疾病方面的潜在作用提供了有价值的见解。

CFD Analysis of Airborne Pathogen Disinfection in a UV-C Air Purification Device

Abstract Numerical simulations of the airflow inside a portable air purification device have been carried out. The simplified system geometry is comprised of key components – fans, particle filters and UV lamps for disinfection, which are included in the model. The study investigates the velocity distribution, UV irradiance, and its impact on air disinfection. The effects of the flow rate and UV dose on the purification efficacy have been investigated. The findings provide valuable insights for optimising the design and configuration of air purification devices, and their potential role in reducing the transmission of airborne diseases.
