DESCRIPTION:Paper\n\nSimulation of Droplet Dispersion in COVID-19 Type Pan
 demics on Fugaku\n\nBale, Li, Yamakawa, Iida, Kurose...\n\nTransmission of
  infectious respiratory diseases through airborne dispersion of viruses po
 ses a great risk to public health. In several major diseases, one of the m
 ain modes of transmission is through respiratory droplets. Virus laden res
 piratory droplets and aerosols can be generated during coughing, sneezing 
 and speaking. These droplets and aerosols can remain suspended in air and 
 be trans- ported by airflow posing risk of infection in individuals who mi
 ght come in contact with them. With this background, in this work, we pres
 ent a numerical framework for simulation of dispersion of respiratory sput
 um droplets using implicit large-eddy simulations. A combination of discre
 te Lagrangian droplet model and fully com- pressible Navier-Stokes flow so
 lver is employed in this study. The method is applied to analyze cases suc
 h as droplet dispersion during speech and cough under different environmen
 tal settings. Further- more, the performance of the numerical framework is
  evaluated through strong and weak scaling analysis.\n\nDomain: CS and Mat
