Response against the COVID-19

SASCorp offers its supercomputing, analysis and modeling capabilities to help understand the Covid-19 problem through CFD simulation and in collaboration with the Healzid group. Our simulations have been shown on national television networks, with top-level doctors and virologists relying on them to raise awareness about the potential transmission of COVID-19, provide their recommendations and propose possible solutions. Different scenarios have been simulated to reveal the possible interactions and the role of certain variables such as air conditioning in the mechanics of virus dispersal. Studies that have led to the conclusion that efficient air renewal, where the flow rates, the orientation of the air outlets and inlets and the location of the passage areas in relation to the circulating air flow are carefully studied, significantly reduces the risk of infection. For all these simulations, the infection process has been modeled in terms of concentration and time, where each individual exhales and inhales a volume of air corresponding to normal respiration during the simulated activity. In addition, the temperature and thermal radiation of each person are included, in order to study the effect of convection on the dispersion mechanics of the aerosol. Our great calculation capacity allows us to carry out large-scale simulations with a high degree of detail, which model the dispersion of aerosols in the field, giving more precise and real results than conventional calculations using particles.
