Flow Visualization, Design & Testing, Prototyping
The device is based on the jet pump principle but it allows for the flow to be reversed with minimal flow resistance. The jet sizes, flow rates and pressures were determined analytically to meet the customer’s specifications. The prototype device worked as predicted.
We used flow visualization with laser sheet light and fluorescent particles in water to determine the optimum placement of the jets and other features in the device. The flow visualization was conducted in water with the scale adjusted to match Reynolds number.
We used a Labview based data acquisition system to make measurements of the pressure and flow during simulated breathing cycles. The data was used to optimize the design.
Cardinal engineers took the fluid pathway that we developed and designed a device which is less harmful to the baby’s nose than competitor products.
