About this model
I designed this thing to improve the efficiency of axial part cooling fans. Axial fans are good at moving high volumes of air at a low pressure. One problem with a ducted axial fan though, is the big negative pressure vortex behind where the hub, or motor is. Filling that volume with a cone really smooths out the air flow inside the duct. Another issue with axial fans is efficiency drops as back-pressure increase more rapidly than it does with radial fans. What happens is that the air starts to spin around with the fan blades. If it's spinning around with the blades, it's not being pushed along the axis of the fan. To visualize this property, imagine if you blocked off both sides of the fan by laying anything flat like card stock and turned it on. In this case you have zero flow, and what …
