Numerical Investigation on Diffusion Length, Suspending Time, and Forces Acting on COVID-19 Virus Particles in an Indoor Environment
Author(s): Mahdi Bagherian Dehaghi* and Mehrzad Shams
The purpose of this study is to study two-dimensional CFD simulations of the COVID-19 virus two phase flows in
steady air with the Euler-Lagrange method. This was accomplished by developing CFD programs in MATLAB and
simulations in COMSOL software. Brownian, drag, saffman, and weight forces are considered for studying the
dynamics of virus flow. In order to study the motion of viruses, brownian, drag forces, and the weight of viruses play
an important role. In this study, three different diameters of virus particles were considered, with three different
initial conditions and three different initial velocities. The diffusion length and suspending time of viruses in the air
have been computed in each of the nine states. .. View more»
