On The Democratization of the Fluid Flow Simulation

- In this paper, we aim to introduce the web-based application called dynairix. Dynairix is a free online tool developed by our team to make the invisible part of pandemics and epidemics visible to the general public. Having a strong background in the field of Computational Fluid Dynamics (CFD), our team has been using it so far primarily in the development of simulation solutions for the automotive production. Now we want apply this know-how in new areas too. The core of dynairix is based on quasi steady CFD results using lattice Boltzmann method (LBM) coupled (one-way) with the Lagrangian particles tracking method. Using this methodology, our tool calculates the dynamic risk factor and shows the ventilation system and its effects in closed environments. This is something especially useful during any epidemics where viruses are transmitted by aerosols. The calculations are based on the real physics of the simulations of various scenarios. They show that good a ventilation system during pandemics and epidemics can not only be useful but rather extremely beneficial.
