Active fluid (original) (raw)
An active fluid is a densely packed soft material whose constituent elements can self-propel. Examples include dense suspensions of bacteria, microtubule networks or artificial swimmers. These materials come under the broad category of active matter and differ significantly in properties when compared to passive fluids, which can be described using Navier-Stokes equation. Even though systems describable as active fluids have been observed and investigated in different contexts for a long time, scientific interest in properties directly related to the activity has emerged only in the past two decades.

| dbo:abstract | An active fluid is a densely packed soft material whose constituent elements can self-propel. Examples include dense suspensions of bacteria, microtubule networks or artificial swimmers. These materials come under the broad category of active matter and differ significantly in properties when compared to passive fluids, which can be described using Navier-Stokes equation. Even though systems describable as active fluids have been observed and investigated in different contexts for a long time, scientific interest in properties directly related to the activity has emerged only in the past two decades. These materials have been shown to exhibit a variety of different phases ranging from well ordered patterns to chaotic states (see below). Recent experimental investigations have suggested that the various dynamical phases exhibited by active fluids may have important technological applications. (en) Un fluido activo es un material blando denso cuyos constituyentes pueden autopropulsarse. Los ejemplos incluyen suspensiones densas de bacterias, redes de microtúbulos o nadadores artificiales. Estos materiales caen en la amplia categoría de materia activa y difieren significativamente en sus propiedades comparándolas con las de los fluidos pasivos, que pueden describirse utilizando la ecuación de Navier-Stokes. Aunque los sistemas clasificables como fluidos activos se han observado e investigado en diferentes contextos durante un largo tiempo, el interés científico en las propiedades directamente relacionadas con la actividad ha aumentado únicamente en las últimas dos décadas. Estos materiales han mostrado una gran variedad de fases diferentes desde los patrones bien ordenados hasta estados caóticos. Las investigaciones experimentales recientes han sugerido que las distintas fases dinámicas exhibidas por los fluidos activos pueden tener importantes aplicaciones tecnológicas. (es) |
