Ontopic: Could a 55-gallon drum substitute for the captured vortex? On powered rollers for A-B testing? |
If you did that, the 'boundary' of the drum's surface would induce the Magnus- effect, like the experimental ship 'sails', and all rifled bullets, and artillery rounds, creating lift due to the low pressure of the boundary layer, dragged around the circumference and acting against the oncoming flow.

To simulate the bed vortex, you'd have to come up with some sort of horizontal version of what Dr. T. Theodore Fujita created in his lab. to study tornadoes. You'd have an all-air phenomena rather than a bounded system.
That would be fun!
