Homework Help: Fluid Flow

    I understand that there can be turbulent flow and laminar flow. However, there is a term 'eddies/eddy' related to this which is not explained in my textbooks. What is an 'eddies/eddy'? :confused:

    Thanks in advance.

    An eddy is one of those little "swirls" of fluid that forms when a fluid flows past an obstacle in its path.

    These current have an analog in electrical currents as well. For instance a changing magnetic field can induce circular currents of electrons in a metal. This circular electron currents are also called eddy currents or "eddies."

    So, does an 'eddy/eddies' only occur on a laminar flow as it does not pass the obstacle in its path?
