William K.'s response is correct. Going a little farther, once the heat is in the plenum air laminar vs turbulent doesn't matter so much. What matters most is the volume of heated air leaving the system. High volume usually means high speed and turbulent.
The evaluation in the blog is correct in asserting that turbulent flow is much better for heat removal, and the reason goes a bit further as to why laminar flow does not pick up heat as well. In a truely laminar flow situation the fluid molecules next to the surface may not be moving at all, and the next layer are moving very slowly, with a classical velocity gradient up to the fastest moving molecules, which are usually those farthest from the wall. The result is that heat is primarily transfered to the air br conduction through the stagnant layers. This is the mechanism of laminar flow's poorer performance.
Not the most exciting explanation in the world, but some useful background stuff.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
The 3D printing revolution seems to have a knack for quickly moving technology ahead by way of collaborative effort and even a little friendly competition -- all of course in the name of scientific advancement.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
