Creating a pulsating water flow with a paddlewheel.
Creating a pulsating water flow with a paddlewheel.
(OP)
I am trying to make a prototype of a new kind of pulsating machine similar to the pulsations and water pressure seen in a Water Pick(Oral Irrigation) device. I am going to try to use a paddle-wheel mounted inside a water tight cylinder that barely circumscribes the paddle-wheel. The entering pipe will be positioned parallel to the exiting pipe and will be located near the edge of the paddle-wheel for the larger moment force. There will also be a one way air valve attached to the cylinder. Now I think the device will pulsate, but I don't know if it will because of temporary pressure change when the paddle-wheel blocks the exit or if it will because of air being sucked into the system. Anyone have any advice??

If it ain't broke, don't fix it. If it's not safe ... make it that way.

But those don't "pulsate" when they add pressure to a system, why would expect the waterwheel to pulse? If the wheel is restricted (by a brake or by friction) wouldn't that be a wear point or fouled by deposits and scum/biologics buildup?
