论文摘要
众所周知，几种病毒以及SARS-COV-2可以通过空气传播的唾液微作用的扩散来传播。因此，许多复原群已经付出了努力，以便获得对人类呼吸道产生的液体和颗粒的运输的新见解。本文旨在为生物美感溶胶的数值建模提供贡献。特别是，进一步研究了在没有外风的情况下避免病毒传播的安全距离周围的众所周知的问题。因此，引入了能够评估污染风险的新索引，并研究了通过外部UV-C辐射源灭活病毒颗粒的可能性。为此，提出了一个新的模型，该模型考虑了在Eulerian-Lagrangian框架中从UV-C暴露中引起的生物学灭活。
It is well known that several viruses, as well as SARS-CoV-2, can be transmitted through airborne diffusion of saliva micro-droplets. For this reason many reserach groups have been devoted their efforts in order to gain new insight into the transport of fluids and particles originted from human respiratory tracts. This paper aims to provide a contribution to the numerical modelling of bio-aerosols. In particular, the well-known problem around the safety distance to be held for avoiding virus transmission in the absence of external wind is further investigated. Thus, new indexes capable of evaluating the contamination risk are introduced and the possibility to inactivate virus particles by means of an external UV-C radiation source is studied. For this purpose, a new model which takes into account biological inactivation deriving from UV-C exposure in a Eulerian-Lagrangian framework is presented.
