论文摘要
在当前正在进行的大流行Covid-19的不幸事件中，疫苗接种开发仍处于初始阶段，已经推荐了卫生专业人员和组织的几项预防控制措施，例如社会疏远，手工觉得和个人保护设备。其中，面部面包的安全穿着在减少传染性呼吸道疾病传播的可能性和严重性方面发挥了至关重要的作用。据报道，Facemasks的研究涵盖了许多材料类型，制造技术，机制表征和应用方面。然而，在最近的时候，焦点已转向对富含病毒颗粒的液体流动机制预防液体流动机制的理论研究。这个令人兴奋的研究领域旨在解决复杂的液体运输，从而导致设计面孔的性能更好。这篇评论论文讨论了通过Facemasks进行流体流动动力学的最新更新。讨论了关键的设计方面，例如热舒适性和阻力。此外，提出了有关面部面包效应预防Covid 19扩散和佩戴面罩的影响的最新进展。最后，突出显示了分析流体流动行为的潜在研究方向。
In the unfortunate event of current ongoing pandemic COVID-19, where vaccination development is still at the initial stage, several preventive control measures such as social distancing, hand-hygiene, and personal protective equipment have been recommended by health professionals and organizations. Among them, the safe wearing of facemasks has played a vital role in reducing the likelihood and severity of infectious respiratory disease transmission. The reported research in facemasks has covered many of their material types, fabrication techniques, mechanism characterization, and application aspects. However, in more recent times, the focus has shifted towards the theoretical investigations of fluid flow mechanisms involved in the virus-laden particles prevention by facemasks. This exciting research domain aims to address the complex fluid transport that led to designing a facemask with a better performance. This review paper discusses the recent updates on fluid flow dynamics through the facemasks. Key design aspects such as thermal comfort and flow resistance are discussed. Furthermore, the recent progress in the investigations on the efficacy of facemasks for prevention of COVID 19 spread and the impact of wearing facemasks are presented. Finally, the potential research directions for analyzing the fluid flow behavior are highlighted.
