Viral Fate & Transport for COVID-19
Investigator: Ramesh Balakrishnan
Affiliation: Argonne National Laboratory
Funding: DOE Office of Biological and Environmental Research
Potentially infectious sites are created when COVID-19 carrying aerosol particles are released as a person talks/sings/coughs/sneezes/breathes and the virus is deposited on the ground and other surfaces. This team is studying how this process occurs in a model classroom setting.
Simulations are carried out by the highly scalable spectral element code, Nek5000, that has been tuned to run on Intel KNL platforms like NERSC’s Cori. The team is using large eddy simulations (LES) of the turbulent flow with aerosol particles to study the dispersion and deposition of the aerosols. The calculations simulate a classroom using about 1 billion grid points and 100K to 250K aerosol particles.
