  1. Emergency Ventilator Device Group 12 Advisor: Dr. Paul King James Grotting Tim Weaver Ryan Winter Josh Gess Whitt Israel

  2. Prototyping • Device – 1:18 cold-rolled plate of steel • Prototype – PVC piping • Cheaper • Easy access to pre-cut tubing • Same effect as steel

  3. Prototype Testing Variables - Inner diameter - Inlet velocity via inlet diameter Constants - 1/4” thick walls - Inlet angled tangential

  4. Future Prototype Testing • Create Labview Virtual Instrument • Catheters • Flowmeters • Pressure vs. Time • Velocity vs. Time

  5. Fluid Mechanics • Interview with Dr. Stremler • Reverse Whistle • Pressure Changes • Inlet Air Flows Along Wall • Ball/No Ball

  6. 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

  7. 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.
