Cough	Temperature	37°C
	Droplets' diameters	2: 2000 μm
	Ingredients	10.4% NaCl & 89.6% water
Inflow	Air velocity	V = 0, 1, 3.9, & 5.5 m/s		V = 5.5 m/s

	Relative humidity	RH = 40% & RH = 99.5%		RH = 40%
Mesh		High-resolution hexahedral grid meshes were generated using Ansys 14.5 Meshing. The minimum dimension of cells equals:
		0.0001 m		0.001 m owing to a mesh independence study
		in regions close to the injection of COVID-19 droplets, with a growth rate of less than 1.2 between sequential cells. The final number of the computational cells:
		3,257,192 cells		1,075,552 cells
Time duration		Intel (R) Core (TM) i7-7700 CPUs, 3.60 GHz processors, and 32 GB of RAM memory per computer used to simulate 0.4 s, every numerical simulation occupied approximately:
		72 h with a time step =  0.0001 s		140 h with a time step = 0.001 s, due to time step analysis
Measuring points		The point of respiratory organs of
		standing humans, at 1.5 m high	sitting humans, at 1.1 m high
