This tunnel achieves laminar flow using an array of soda straws to direct the flow. In fact, there are 150 straws in total. You can see a short clip of the wind tunnel in action below.

The flow thereafter remains laminar unless it is disturbed again. "Nobody knew that it was possible to get rid of turbulence in practice. We have now proven that it can be done.

Boeing plans to reduce airframe drag on the 787 by standardising on a specific thickness of grey paint for the engine inlet, to preserve natural laminar and boost range.

Studying the transition from a linearly stable coherent laminar state to a highly disordered state of turbulence is conceptually and technically challenging, and of great interest because all pipe ...

The laminar nozzle shown in the picture above is built with 800 drinking straws all placed in parallel inside a 4″ PVC pipe. The water input is a 3/4″ garden hose adapter, perpendicular to the ...
