The design of a coughing and sneezing machine
thesisposted on 2022-03-28, 15:47 authored by Joshua Scrivener
Virus transmission is an imminent threat to humans and animals. Influenza primarily spreads from an infected host via means of direct contact, but also airborne mediums such as coughing and sneezing. Currently there is very limited factual and numerical information that exists regarding airborne virus transmission. In this project, a novel machine is designed and constructed to accurately simulate human respiratory actions and physiological variables. Having the ability to accurately and repeatedly simulate human respiratory actions will allow physiological variables such as velocity, viscosity, droplet size and dispersed fluid volume to be analysed for their contribution to virus transmissibility. This thesis paper provides all work involved in designing, constructing and testing the machine prototype. This thesis project will be particularly useful for Macquarie University's industry partner, World Health Organisation.
