Contaminant flow and personal exposure

Contaminant flow and personal exposure

When displacement ventilation is applied, air exhaled through the mouth can be "locked" in a thermally stratified layer where concentrations several times greater than the return concentration may occur (Photo D). In these situations, the boundary-layer flow around the body offers some pro...

Zusammenfassung:When displacement ventilation is applied, air exhaled through the mouth can be "locked" in a thermally stratified layer where concentrations several times greater than the return concentration may occur (Photo D). In these situations, the boundary-layer flow around the body offers some protection.
