Abstract
Recently, COVID-19 has spread throughout the world, causing confusion among society and people. It is important to establish a framework for countermeasures against infectious diseases so that the outbreak will be under control in the near future and people can once again enjoy their lives and travel with peace of mind. In this study, it is proposed to evaluate whether the air in hotel rooms is correctly cleaned when air purifiers are installed, and to establish a framework for quantitative evaluation of safety against COVID-19 infection based on numerical fluid an analysis using OpenFOAM. The numerical models are measured at the Miyazaki Kanko Hotel. The flow field is assumed to be a three-dimensional, unsteady, incompressible viscous flow. Boundary conditions are given as velocities at the inlet and outlet surfaces based on the measured data. Nonslip conditions are set for the walls. This analysis uses RANS for turbulence analysis of the three dimensional incompressible viscous flow. The present analysis provides a visualization of the flow in a room, which is the basis for evaluating safety.
