AIR ENTRAINMENT Meaning and
Definition
-
Air entrainment refers to the process of intentionally introducing air or gases into a fluid, typically a liquid or a mixture, in order to create air bubbles or pockets within the substance. This phenomenon is commonly used in various engineering, scientific, and industrial applications.
In the context of fluid dynamics, air entrainment occurs when air is entrapped or captured within a fluid due to the turbulent flow of the substance. This occurs when the fluid is rapidly agitated or forced through a constriction, resulting in the formation of tiny air bubbles dispersed throughout the liquid or mixture.
Air entrainment has various practical uses. In industries such as wastewater treatment, air entrainment is employed to enhance the oxygen transfer efficiency in aeration tanks, fostering the growth of aerobic microorganisms that consume organic matter. It is also utilized in concrete production to improve its workability and reduce its weight without compromising its strength. Additionally, air entrainment is crucial in the design and operation of pumps to prevent cavitation, which is the formation of air or vapor pockets that can damage the internal components.
Furthermore, air entrainment plays a significant role in nature. In the case of breaking ocean waves, air entrainment occurs as air is mixed and trapped within the water, resulting in the formation of white foam and bubbles. This phenomenon is associated with the natural process of bubble-mediated gas exchange between the ocean and the atmosphere, affecting climate and the cycling of important gases.

Etymology of AIR ENTRAINMENT
The word "air entrainment" can be analyzed by breaking it down into its constituent parts: "air" and "entrainment".
The term "air" derives from the Old English word "ǣr", which means "gas" or "breath". This can be traced back to the Proto-Germanic word "aizaz", meaning "vital breath" or "life-giving gas".
The word "entrainment" comes from the verb "entrain". "Entrain" was formed by adding the prefix "en-" (meaning "into" or "on") to the French word "train", which originally referred to a "track" or a "path". Over time, "entrain" came to mean "to get on board a train" or "to get into motion". Eventually, the term extended its meaning to include "to incorporate" or "to take in".
