Fluid dynamics

Definition

Fluid dynamics is the study of the motion of liquids, gases and plasmas. Flow is dependent on the intrinsic properties of the matter itself, such as compressibility, viscosity and density. Example systems are a liquid flowing through a pipe or capillary, air moving across an aeroplane wing, and plasma motion in a stars magnetic field.

    When a particle-laden droplet evaporates on a solid surface, the particles form a ring-like deposit. The explanation for this phenomenon, provided in 1997, has led to advances in many areas of science and engineering.

    Vast beds of 'hair' coat many living systems, and usually exhibit shear-thinning behaviour — their flow resistance lessens with speed. But with geometric tweaks, such beds can also show shear-thickening and asymmetric ratchet-like behaviour.

    Assigning dimensions to physical quantities is not just for practicality. Steven T. Bramwell reflects on the deeper physical connotations of it all.

    Topological states of matter offer new opportunities to improve the way we transmit acoustic or optical signals, but existing technologies have proven difficult to scale. The field of active metamaterials may be able to help.
