Definition of hydrodynamics in English:


plural noun

  • [treated as singular] The branch of science concerned with forces acting on or exerted by fluids (especially liquids).

    • ‘His early work was on magnetism and electricity but he soon concentrated on hydraulics and hydrodynamics.’
    • ‘His interests in science itself were mainly in the area of mathematical physics, and in particular thermodynamics, hydrodynamics, elasticity, mathematical chemistry, and mechanics.’
    • ‘He was interested in their applications to dynamics, hydrodynamics, elasticity, and electrostatics.’
    • ‘Sailing is one of those sports which involves hydrodynamics, fluid dynamics, material science, human physiology, tactics, psychology.’
    • ‘His work on machines includes much in the area of applied mechanics, but he was also interested in applied hydrodynamics and steam engines.’
    • ‘Two further works, one on the mathematical theory of heat and the other on hydrodynamics, were in preparation at the time of his death.’
    • ‘Jeffrey's work was on the applications of mathematics, in particular he worked on hydrodynamics, viscous liquids and elasticity.’
    • ‘In particular he applied his methods to equations resulting from electromagnetics, then later to those arising from hydrodynamics.’
    • ‘He was also interested in hydrodynamics and hydraulics and he moved on from making sundials to invent other machinery, in particular pumps.’
    • ‘Current research focuses on the forces that act on a body moving through the water, the science of hydrodynamics.’
    • ‘We could not understand chemistry and hydrodynamics.’
    • ‘Thus, the lipid dynamics depend on the friction and not on hydrodynamics.’


Late 18th century: from modern Latin hydrodynamica, from Greek hudro- water + dunamikos (see dynamic).
