Entrainment as commonly used in various branches of science and engineering may be defined as the entrapment of one substance by another substance.[1][2]
Types of entrainment
Ther are a great many types of entrainment encountered in chemistry, chemical engineering, other engineering disciplines and in atmospheric sciences. Here are a number of examples:
- The entrapment of liquid droplets in air or any other gas as in aerosols or fog or spray painting.
- The entrapment of liquid droplets and solid particulate matter in a flowing gas, as in smoke entrapped in combustion flue gases.
- 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 entrapped in the other liquid, as with margarine.
- Given two gases, the entrapment of one gas into the other gas.
- The intentional entrapment of air bubbles in concrete.
- The entrapment of solid particles in an air or other gas as in fluid catalytic cracking, fluidized combustion and many other processes utilizing fluidized solids.
