Abstract

The sudden spread of Covid-19 in the world has attracted everyone's attention. In addition, due to the unknown and lack of definitive treatment methods, the World Health Organization and other medical institutions recommend non-pharmacological solutions to control the virus. In this regard, one of the proposed methods is to use masks during this global epidemic as a tool to control the spread of respiratory droplets. Therefore, in this paper, we first examine respiratory events such as breathing, talking, sneezing, and coughing from an engineering perspective and their role in the spread of the virus. In addition, with the help of numerical fluid mechanics, the formation of respiratory droplets and their function in the transmission of infectious respiratory diseases have been studied. Then, the necessity of using a mask and its role in reducing the transmission of the virus is discussed.
