Laminar and turbulent flow, the liquid or object?

  1. Apr 19, 2015 #1
    Please could someone verify this statement as I understand things:

    If an object has a low reynolds number (or the fluid is very viscous) then it is dominated by viscous forces and inertia plays no role. The object is in a laminar flow regime.

    That last part, is it correct? What I'm asking is, is it the object laminar flowing or is it the liquid that is laminar flowing?

    Thanks for any help clearing this up.

    The term laminar flow applies only to fluids, not objects.

    Thanks for the reply.

    So you would say, the object is subject to a laminar flow regime?

    No. If I understand you correctly, rigid objects to not exhibit laminar flow.

    You would say the flow around the object is laminar.
