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.
