The fastest supercomputer in 2020, Fugaku, has not only achieved digital transformation of epidemiology in allowing end-to-end, detailed quantitative modeling of COVID-19 transmissions for the first time but also transformed the behavior of the entire Japanese public through its detailed analysis of transmission risks in multitudes of societal situations entailing heavy risks. A novel aerosol simulation methodology was synthesized out of a combination of a new CFD methods meeting industrial…

Effects of inbound attendees of a mass gathering event on the COVID-19 epidemic using individual-based simulations

The simulation results indicated that the increase in the number of patients with COVID-19 could possibly be suppressed to a level equivalent to that if the event were not being held so long as the prevalence among visitors was only slightly higher than that among domestic residents and strict requirements were applied to the activities of visitors.

Simulation of droplet dispersion in COVID-19 type pandemics on Fugaku

A combination of discrete Lagrangian droplet model and fully compressible Navier-Stokes flow solver is employed in this study and the method is applied to analyze cases such as droplet dispersion during speech and cough under different environmental settings.

Quantifying the COVID19 infection risk due to droplet/aerosol inhalation

A version of the model is introduced that can incorporate the higher transmissibility of variant strains of SARS-CoV2 and the effect of vaccination in evaluating the probability of infection in droplet dispersion simulations using the dose-response model.

A Scalable Framework for Numerical Simulation of Combustion in Internal Combustion Engines

A numerical framework based on the hierarchical meshing technique building cube method for modelling internal combustion engines efficiently combines a fully compressible flow solver, chemical reaction and combustion model, a particle-in-cell based liquid spray model, and an immersed boundary method for geometry treatment.
