Abstract
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 to uncover the interfacial phenomena involved in bioaerosol generation during forceful breathing actions like coughing or sneezing. By investigating these fluid-mechanical processes, we aim to establish a foundation for optimizing mitigation strategies and promoting public health and well-being.
