Abstract:
1. A decontamination system comprising: a decontaminant reservoir; a transport fluid source; and a mist generating apparatus having a longitudinal axis, the apparatus comprising: a curved divergent-convergent first fluid passage having a first fluid inlet in fluid communication with the decontaminant reservoir, the first fluid inlet defining an inlet area, an annular first fluid outlet defining an outlet area, and an intermediate portion defining an intermediate area greater than each of the inlet area and the outlet area, the curved divergent-convergent first fluid passage having an outer surface with a curved profile between at least the intermediate area and outlet area; and a convergent-divergent second fluid passage having a second fluid inlet in fluid communication with the transport fluid source and an annular second fluid outlet, wherein the first fluid passage surrounds the second fluid passage, and the first and second outlets are oriented relative to one another such that they have an angle of incidence between 5 and 30 degrees; wherein a cross-sectional area of the second fluid outlet is larger than a cross-sectional area of the first fluid outlet; and the second fluid passage includes a throat portion located between the second fluid inlet and the second fluid outlet, the throat portion having a smaller cross sectional area than that of either the second fluid inlet or second fluid outlet.
