TITLE

Assistant Professor Ishii Keiko (Gerontology Research Laboratory, College of Science and Engineering, Department of Electrical Engineering and Electronics) explicates the physics of human exhalation diffusion in face-to-face scenario with utterance, and its use in prevention measures for COVID-19.

CATEGORY

The research paper by Assistant Professor Ishii Keiko (Gerontology Research Laboratory, College of Science and Engineering, Department of Electrical Engineering and Electronics) and co-workers, “Relationship between human exhalation diffusion and posture in face-to-face scenario with utterance”, was published in “Physics of Fluids” by the American Physical Society, being chosen as a “Featured Article”. The article was also press released on the AIP publishing website alongside a commentary article.

The research was made as a project of the Gerontology Research Laboratory, in cooperation with Professors Onishi Noriko, Ohno Yoshiko, and Oikawa Maiko (Associate Professor) of Yamano College of Aesthetics. The research visualized the flow of exhaled air during conversations and customer services, in order to improve prevention measures for COVID-19.

The research discovered how, from the perspective of thermal hydraulics, the flow of exhaled air is affected by human body surface temperature, posture, and the presence or absence of masks and face shields. The research was praised for providing insight into the prevention of aerosol infections for face-to-face customer services, and revealing a previously unreported physics of exhaled air.
