Eulerian Coordinates

Any system of coordinates in which properties of a fluid are assigned to points in space at each given time, without attempt to identify individual fluid parcels from one time to the next. See equations of motion. Compare Lagrangian coordinates. </dd>
Eulerian coordinates are to be distinguished from Lagrangian coordinates. The particular coordinate system used to identify points in space (Cartesian, cylindrical, spherical, etc.) is quite independent of whether the representation is Eulerian or Lagrangian. [[/a>|/a> ]]
