“…O equipamento gerador de aerossol utilizado foi configurado para gerar partículas de tamanho médio 4,0 µm ± 1,1 µm e concentração máxima na ordem de 1,2x10 6 partículas/cm 3 , valores estes equivalentes às gotículas exaladas em espirro contínuo [23]. O gerador de aerossol fornece vazão entre 3,5 e 4,0 ℓ/min., valores estes semelhantes à vazão média de ar de inalação e exalação das pessoas [24]. Para simular a fonte contaminante, foi utilizada a substância DEHS, que se mostrou bastante adequada para este tipo de ensaio, por possuir propriedades semelhantes às da água (ρ=915 kg/m…”

“…In fact, most of the latex particles were transported within a short distance from the coughing person in the first 30 s and then could be transported to the entire space with a uniform droplet distribution in 4 min (Gupta et al, 2011). As the source location significantly affects the pollutant transport within an aircraft cabin (Yan et al, 2009), the use of downward plane jet to separate the space into a few sub zones may minimize the transport of respirable particles of a cough from the source.…”

“…It indicates that a cough jet may not penetrate the downward jet and reach the breathing zone directly. In another words, a vertical downward plane jet (two-jet) method with a higher initial momentum may prevent the transport of virus or bacteria after coughing, which may affect the local micro-environment and the entire indoor environment effect due to the mixing airflow in a space (Yan et al, 2009) (a) average personal exposure value of the exposed dummy to a cough from a source dummy with DPJ (two-jet) (b) instantaneous personal exposure value of the exposed dummy to a cough from a source dummy in case 5, (c) instantaneous personal exposure value of the exposed dummy to a cough from a source dummy in case 8.…”
