gasentrained
Gas entrained refers to the presence of gas within a liquid flow, resulting in a gas–liquid mixture or foam. It occurs when gas is captured and carried by the moving fluid, either from a free surface during turbulence or from local pressure changes that generate bubbles. Entrainment can involve ambient air or dissolved gases released into the liquid.
In natural systems, gas entrainment is common in fast-flowing rivers, rapids, and waterfalls where turbulence pulls
Key implications of gas entrainment include enhanced mass transfer of gases to or from the liquid, which
Measurement and control centers on quantifying gas hold-up or void fraction and the bubble size distribution.
