Giving off bubbles and developing a head of foam; as, a foaming glass of beer.
In a boiler, the carry-over of slugs of water into the piping due to dirty water or overloading of the boiler. Compare PRIMING.
The continuous formation of bubbles which have sufficiently high surface tension to remain as bubbles beyond the disengaging surface.
A condition that occurs when an organic substance, usually oil, is floating on the surface of the water in a boiler. This generally is indicated in the gauge glass by large swings in water level.
A laser process where the laser heats the surface of a plastic material to the boiling point, trapping air bubbles in the material as it cools. Creates a textured mark, usually with some color contrast.
emitting or filled with bubbles as from carbonation or fermentation; "bubbling champagne"; "foamy (or frothy) beer"
covered with or resembling small bubbles as from being agitated by beating or heating; "the bubbling candy mixture"; "a cup of foaming cocoa"; "frothy milkshakes"; "frothy waves"; "spumy surf"
A mass of gas bubbles in a liquid film matrix, esp. a light, bubbly gas and liquid mass formed by agitating a liquid containing certain soaps or detergents.
Development and persistence of bubbles on the surface of fats during frying operations. Persistent foaming and accumulation of thick layers of foam may be indicative of fat breakdown.
A condition created by agitation and related to surface tension of the liquid.
A term used to describe surface foam on your water, esp in spas/hot tubs. Foaming is caused by high TDS levels working in combination with soft water and oils. Certain low grade algaecides can foam when added to pool or spa. Use enzymes for foam control.
Formation of steam bubbles on the surface of boiler water due to high surface tension of the water. See carryover.
