Prototyping

Prototyping

  • Device – 1:18 cold-rolled plate of steel

  • Prototype – PVC piping

  • Cheaper

  • Easy access to pre-cut tubing

  • Same effect as steel


Prototype

Prototype

Testing Variables

- Inner diameter

- Inlet velocity via inlet diameter

Constants

- 1/4” thick walls

- Inlet angled tangential


Future prototype testing

Future Prototype Testing

  • Create Labview Virtual Instrument

  • Catheters

  • Flowmeters

  • Pressure vs. Time

  • Velocity vs. Time


Fluid mechanics

Fluid Mechanics

  • Interview with Dr. Stremler

  • Reverse Whistle

  • Pressure Changes

  • Inlet Air Flows Along Wall

  • Ball/No Ball


Pneumatic actuators

Pneumatic Actuators

  • The more certain but more expensive approach to accomplishing goal

  • Air Pressure powers valve

  • Wall Pressure would be diverted from wall to both bulk volume ventilator in parallel with actuator and valving


Achieving oscillations through acoustics

Achieving oscillations through acoustics

  • Interview with Ken Frampton

  • Problems with design

  • Poor results at low frequencies

  • Maximizing displacement

  • Need for large amplifier and power source

  • Overcoming high back pressure at outlet valve.
