Entrainment may refer to: *

Air entrainment Air entrainment in concrete is the intentional creation of tiny air bubbles in a batch by adding an air entraining agent during mixing. A form of surfactant (a surface-active substance that in the instance reduces the surface tension between wate ...

, the intentional creation of tiny air bubbles in concrete *

Brainwave entrainment Brainwave entrainment, also referred to as brainwave synchronization or neural entrainment, refers to the observation that brainwaves (large-scale electrical oscillations in the brain) will naturally synchronize to the rhythm of periodic external ...

, the practice of entraining one's brainwaves to a desired frequency *

Entrainment (biomusicology) Entrainment in the biomusicological sense refers to the synchronization (e.g., foot tapping) of organisms to an external perceived rhythm such as human music and dance. Humans are the only species for which all individuals experience entrainmen ...

, the synchronization of organisms to an external rhythm *

Entrainment (chronobiology) In the study of chronobiology, entrainment refers to the synchronization of a biological clock to an environmental cycle. An example is the interaction between circadian rhythms and environmental cues, such as light and temperature. Entrainment ...

, the alignment of a circadian system's period and phase to the period and phase of an external rhythm *

Entrainment (engineering) In engineering, entrainment is the entrapment of one substance by another substance. For example: * The entrapment of liquid droplets or solid Solid is a state of matter where molecules are closely packed and can not slide past each other. ...

, the entrapment of one substance by another substance *

Entrainment (hydrodynamics) Entrainment is the transport of fluid across an interface between two bodies of fluid by a shear-induced turbulent flux. Entrainment is important in turbulent jets, plumes, and gravity currents, and is an ongoing topic of research. History T ...

, the movement of one fluid by another *

Entrainment (meteorology) Entrainment is a phenomenon in the atmosphere that occurs when a turbulent flow captures a non-turbulent flow. It is typically used to refer to the capture of a wind flow with high moisture content or in the case of tropical cyclones, the capture o ...

, a phenomenon of the atmosphere *

Entrainment (physical geography) In physical geography, entrainment is the process by which surface sediment is incorporated into a fluid flow (such as air, water or even ice) as part of the operation of erosion Erosion is the action of surface processes (such as Surface runof ...

, the process by which surface sediment is incorporated into a fluid flow *

Entrainment (physics) Injection locking and injection pulling are the frequency effects that can occur when a harmonic oscillator is disturbed by a second oscillator operating at a nearby frequency. When the coupling is strong enough and the frequencies near enough, th ...

, the process whereby two interacting oscillating systems assume the same period *

Lexical entrainment Lexical entrainment is the phenomenon in conversational linguistics of the process of the subject adopting the reference terms of their interlocutor. In practice, it acts as a mechanism of the cooperative principle in which both parties to the conv ...

, the process in conversational linguistics of the subject adopting the terms of their interlocutor *

Photoentrainment (chronobiology) In chronobiology, photoentrainment refers to the process by which an organism's biological clock, or circadian rhythm, synchronizes to daily cycles of light and dark in the environment. The mechanisms of photoentrainment differ from organism to orga ...

, the synchronization by light of organisms to environment rhythm
