Bag-mediated film atomization in a cough machine

Studying the fluid dynamics of exhalations, from droplet formation to turbulent cloud transport, is vital for understanding respiratory disease transmission. Our research combines experiments and numerical modeling uncover interfacial phenomena involved in bioaerosol generation during forceful breathing actions like coughing or sneezing. By investigating these fluid-mechanical processes, we aim establish a foundation optimizing mitigation strategies promoting public health well-being.
