What he is showing with the airflow in his little chamber is basically right.
If air simply took a direct or shortest path from high to low pressure, planes would not fly and sail boats would not move.
The problem with the rda seems pretty clear to me — massively excessive airflow in a massively excessive chamber with just one coil. Also, not taking into account the effects of friction across the relatively massive distance between the air holes and the coil. But anyway, the path of all that air doesn’t matter — it just can’t work with so much air flowing relative to coil surface area. It’s like a little coil in a hurricane. He didn’t model any of that — he modeled just the path of the (way too much) air. Because of that, I don’t think the blades will help much. A coil making vapor in a hurricane tastes like the hurricane, not the vapor.
