The world's most powerful super used for analysis of behavior #aerosolen . With the new most powerful supercomputer in the world - Fugaku - the Japanese research centre RIKEN has researched the effects of #mondmaskers and mudguards. From simulations of the behaviour of aerosols and droplets, the Japanese researchers draw the conclusions that both are very effective, especially in a working situation.

“One of the reasons why the degree of infection in Japan is so low compared to other developed countries may be the result - or at least partially - because of the work done on Fugaku,” claims Satoshi Matsuoka, director of the RIKEN Center for Computational Science. He spoke yesterday at Fujitsu's online conference ActiveNow.

Mudguards do not make any sense
The beneficial effect measured when using mouthcaps and 'cough' screens does not occur when using mudguards worn on the head, light researcher Makoto Tsubokura, team leader at the RIKEN Research Centre in The Guardian. Those are virtually ineffective in intercepting aerosols is the conclusion from the simulation experiments. Virtually 100 percent of floating drops with a diameter of less than 5 micrometers escape from such a face screen. These screens are often used in the catering industry but also in schools.


Supercomputer says: mouth mask quite effective
