A few years ago Hackaday featured a laminar project ... in parallel inside a 4″ PVC pipe. The water input is a 3/4″ garden hose adapter, perpendicular to the flow of the output nozzle.

This section was adapted from The Engine and the Atmosphere: An Introduction to Engineering by Z. Warhaft, Cambridge University Press, 1997. How many times a day do we turn on a faucet? Do it now.

To do so, we derive an exact solution for laminar profiles of channel flows with an arbitrary, time-varying wall motion and pressure gradient. This solution then allows us to investigate the stability ...

Air Knives are pressurized air plenums containing a series of holes or continuous slots through which pressurized air exits in a laminar flow pattern. The exit air velocity then creates ... They are ...
