A research group consisting of Assistant Professor Keiko Ishii of the Faculty of Science and Technology of Aoyama Gakuin University, Professor Noriko Onishi of Yamano College of Aesthetics, Professor Yoshiko Ohno, and Associate Professor Maiko Oikawa succeeded in visualizing the state of breath flow during customer service and speech. ..The paper published in the American Institute of Physics journal "Physics of Fluids" was highly evaluated as having great expectations for the prevention of new coronavirus infection, and was selected as a noteworthy paper.
According to Aoyama Gakuin University, this research was a joint research with researchers at Yamano College of Aesthetics and Arts as a project of the Gerontology Institute of Aoyama Gakuin University. The flow situation was visualized.
As a result, we succeeded in understanding from the viewpoint of thermo-fluid mechanics how the flow of exhaled breath is affected by the surface temperature of the human body and changes depending on the posture of the person and the presence or absence of a mask and face shield.In this paper, Assistant Professor Ishii and his research group provided findings on the prevention of aerosol infection during face-to-face customer service, and stated that the physics of exhaled breath flow, which had never been reported before, was clarified.
The papers of the research group by Assistant Professor Ishii and others have been press-released and distributed worldwide along with commentary articles on the website of the American Institute of Physics Publishing Bureau.
