RIKEN is implementing a large-scale simulation of virus droplet infection prediction in an indoor environment as a countermeasure against new coronavirus infection using the next-generation supercomputer "Tomitake" that is being carried in and installed at the Kobe office in Chuo-ku, Kobe. Decided to add.
According to RIKEN, this simulation will be carried out in collaboration with RIKEN, Kyoto Institute of Technology, Kobe University, Osaka University, Toyohashi University of Technology, and Kajima Corporation.Utilizing the ultra-large-scale thermo-fluid analysis software that is being implemented in Tomitake, we will accurately simulate how the droplets generated by sneezing, coughing, and conversation float in the indoor air.
In addition, we will perform scattering simulations in various indoor environments such as commuter trains, classrooms, offices, and hospital rooms to quantitatively evaluate the risk of infection, and make recommendations on opening and closing windows and effective operation methods for air conditioners.
Tomitake is the successor to the supercomputer "K computer" and was manufactured by Fujitsu.Initially, it was planned to start operation in 2021, but due to the spread of the new corona, it was decided to move it forward.Four projects have already been adopted: search for new corona therapeutic drug candidates, structural prediction of new corona proteins, pandemic simulation analysis, and fragment molecular orbital calculation for new corona-related proteins.
