CFDと疫学モデルの連成解析による大空間の感染リスク評価解析

抄録

Due to global COVID-19 pandemic, environmental control system design for building and mobility products would be increasingly demanded to ensure comfortable indoor environments, and to ensure the effective biological contamination control. In this paper, 3D simulation tool is introduced to address such brand-new needs by coupling CFD with epidemiological model. The characteristics of anti-activation function was mathematically modeled and incorporated into the coupled analysis. A trial analysis in an office with air-conditioning system showed that 92% infection risk reduction was realized before and after the anti-activation on the air-conditioning. With the developed tool, space design such as HVAC system layout can be proposed to satisfy contamination safety as well as thermal comfort by quantifying and visualizing the change of contamination propagation and infection risk distribution.
