Brief Description: Ghetto cooler flow test rig
|
|
I had this wild hair Idea. If I could somehow direct air into the cooler scoop and use tufts to test the flow through the cooler, I'd be able to see if all the cooler rows are getting air through them. If not, then the additional honeycomb or air vanes would be needed even before test flights. So I went all in, and red neck on this one :)
Using a garbage bag, duct tape, and a leaf blower, I could run that sucker on high and get flow through the cooler. Now, had I just aimed the blower at the inlet, the airflow may have been very different than in flight, so using the garbage bag, I could direct the air away from the scoop ensuring and even flow through the scoop inlet rather than direct. The only thing I'm concerned about is that the flow rate goes way down and pressure goes way up before entering the scoop. However, since I'm only wanting to see correct airflow, the difference shouldn't matter. Air is definitely flowing through the cooler, but much MUCH slower than it's coming out of the blower nozzle. I'm excited to tape up some tufts and see what kind of flow I've got, and then experiment with different mods to get the flow evenly through all 18 rows :) More later...
