Can this be moved to the Unicorn Corall ?
I'm still curious about this though, and asked a math teacher I work with if a windmill draws in any additional airflow once it begins spinning.
He said it probably would
I then called the A&M wind tunnel and got to speak with one of the aerodynamicists.
I asked if the boxfan in the bed of a truck would draw in any additional airflow once it began spinning.
Her answer was " Potentially " - followed by a quick " So is this pertaining to any test you intend to perform here at the tunnel ? " ( Because if not, go away ! Lol )
I certainly do not intend to add fans to my car.
The idea was just a passing curiousity.
I would think that the only extra airflow the fans could provide, would be from a few seconds of momentum as the windspeed changes, and would just be a tiny puff of air.
Useless.
I would imagine that to decrease a cars wake by blowing air into it, you would need a massive amount of wind.
