MATHEMATICAL MODELLING OF JET DEVELOPMENT AND DROPLET DISPERSION DURING SNEEZING: A REVIEW

Abstract

SARS (2003), Swine Flu (2009), Covid-19 are some of the recent global outbreak that spread mainly by airborne respiratory droplets. Sneezing is one of potential sources of transmission of respiratory diseases. It is the need of the hour to study the of human sneeze behaviour. In previous years, several numerical studies were conducted using CFD to foresee the hydrodynamics of particles transmission and penetration during human-forced respiratory activities. Also various surveys were conducted on human sneeze droplet distribution and the effect of relative humidity, inlet velocities on sneeze droplet dispersion in recent years. This report is a review of various methods used by previous studies in the field of human sneezing profile. Literature review on numerical studies on human sneeze jet development and droplet dispersion is done. For better pandemic control caused by airborne transmission of pathogen carrying microbes more detailed study should be performed.
