CFD analysis of the performance of a local exhaust ventilation system in a hospital ward

For that study CFD models have been developed to simulate the transport of infectious droplets and bioaerosols in a hospital ward. Those models will help for the design and control of a local exhaust ventilation (LEV) system. Details of the CFD models are reported in this paper along with the analyses of the distribution and suspension time of droplets and bioaerosols with respect to their size, emission direction and emission speed.
