How do you call an effect, when liquid or gas stream is involving the neighboring layers of matter also move?
Like on videos of rocket engines testing, when exhausting gas sucks an air and steam from behind an engine?

An effect is visible in an inset, where the nozzle is shown from above.
Bladeless fans work on the base of this effect:
Air is emitted by the circle only, but it involves entire mass in the center to move.
Also injector seemedly uses this
Unfortunately it is said it uses Venturi effect, but I need term about movement, not pressure...
