Numerical analysis of the efficiency of face masks for preventing droplet airborne infections
Keiji Onishi, Akiyoshi Iida, Masashi Yamakawa +1
In this study, the flow field around face masks was visualized and evaluated using computational fluid dynamics. The protective efficiency of face masks suppressing droplet infecti…
Digital transformation of droplet/aerosol infection risk assessment realized on "Fugaku" for the fight against COVID-19
Kazuto Ando, Rahul Bale, ChungGang Li +3
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 transmiss…
Topology-free immersed boundary method for incompressible turbulence flows: An aerodynamic simulation for 'dirty' CAD geometry
Keiji Onishi, Makoto Tsubokura
To design a method to solve the issues of handling 'dirty' and highly complex geometries, the topology-free method combined with the immersed boundary method is presented for visco…
CUBE: A scalable framework for large-scale industrial simulations
Niclas Jansson, Rahul Bale, Keiji Onishi +1
Writing high performance solvers for engineering applications is a delicate task. These codes are often developed on an application to application basis, highly optimized to solve…
