Laminar Reverse Flow
August 5, 2008 No Comments
Ever heard of laminar reverse flow?
Don’t feel too bad if you haven’t. You’d need to be a slide-rule-carrying techno-geek to know about it.
But the fact is that it’s a pretty amazing process, which is demonstrated in a short video seen at today’s FamilyFirst pick.
Here’s a summary of what’s going on:
Laminar flow, sometimes known as streamline flow, occurs when a fluid flows in parallel layers, with no disruption between the layers. In fluid dynamics, laminar flow is a flow regime characterized by high momentum diffusion, low momentum convection, pressure and velocity independent from time. It is the opposite of turbulent flow. In non-scientific terms laminar flow is “smooth,” while turbulent flow is “rough.”
What it amounts to is that three drops of food coloring are dropped into a clear cylinder containing white corn syrup. Then, the mixture is agitated by the turning of a cylindrical plunger that distributes the colors evenly, in the forms of strips of color.
THEN, it gets amazing. Watch what happens when the mixture is agitated in the opposite direction!
