Venturi Ejector Draw

venturi-ejector-draw

A processing/analyzing loader shaped as an industrial Venturi vacuum ejector: a particle stream necks through a 22%-of-inlet throat and visibly speeds up there, a second entrainment stream merges in from a side port just before the constriction, and one marked tracer crosses the whole nozzle every 2.4s at full opacity against the ambient field's 55%.
