Course Outline

An eddy is a current created behind a rock or other obstruction, such as a house or car, that flows in a circular upstream direction.

  • The flow of the eddy is opposite to the direction of the main laminar flow.
  • The visual separation between an eddy and the main current is the eddy line. The line is narrow closest to the obstruction and becomes wider downstream.
