Entrainment (engineering)

In engineering, entrainment is the entrapment of one substance by another substance.[1] For example:

  • The entrapment of liquid droplets or solid particulates in a flowing gas, as with smoke.
  • The entrapment of gas bubbles or solid particulates in a flowing liquid, as with aeration.
  • Given two mutually insoluble liquids, the emulsion of droplets of one liquid into the other liquid, as with margarine.
  • Given two gases, the entrapment of one gas into the other gas.
  • "Air entrainment" - The intentional entrapment of air bubbles into concrete.
  • Entrainment defect in metallurgy, as a result of folded pockets of oxide inside the melt.
See entrainment for other types.
