Executive Summary :

The current study aims to model the aerosolised transmission of pathogens via turbulent expiratory events – coughing, sneezing and even exhaling. Many body hydrodynamics of a droplet cluster, mimicking a cough/sneeze will be simulated, to obtain a better understanding of droplet-airborne transmission of diseases. The role of polydispersity, hydrodynamic interactions, background turbulence, preferential concentration and droplet wake dynamics on the ‘cough cloud’ will be studied.

Outcome/Output:

The exit-time for the asymptote of large Peclet numbers wherein the convective effects are dominant.
