On air entrainment in coatings

Journal of Colloid and Interface Science, 2003
A series of experiments that clarify how air bubbles become entrained into coatings are described. The contact line dynamics at the air-liquid interface surrounding a fiber is characterized for a typical coating die operating under atmospheric and pressurized conditions.

Study of Air Entrained Concrete with Various Types of Air Entraining Admixtures

Materials Science Forum, 2022
In current concrete practice, several types of air entraining admixtures are used. These admixtures aim to improve the durability of concrete in aggressive exposure conditions caused by negative temperatures in combination with salts. The current article attempts to describe the types actually used, namely, synthetic tensides and natural resins and to ...

Air Entrainment in Turbulent Liquids

Science, 1961
An experimental technique has been developed for measuring the concentration and distribution of air entrained by turbulence in an agitated liquid. The air content was related to the viscosity, surface tension, and turbulence of the liquid by dimensional analysis.

On the entrainment in nonprecipitating cumuli — Entrained air provenance

Studia Geophysica et Geodaetica, 1985
The paper deals with the testing of the cloud top entrainment hypothesis. The method is based on the works by Warner[1–3], Paluch[4] and Telford[5]. The levels at which the entrained air might originate were determined. Several types of successions of entrainment levels were found; in the upper parts of cumuli, entrainment from above the level of ...

Air entrainment at drops

Journal of Hydraulic Research, 1996
This paper describes the results of a laboratory study of air entrainment below drops for a range of Drop numbers from 0.0007 to 0.0046. Characteristics of the plunging flow that occurs when the tailwaler depth yt is in the range of yt* . to h were studied where yt* . is the value of yt when a hydraulic jump is formed at the section where Ihe deflected
