Title: 5 Gallon bucket separator
Post by: DonJ on March 27, 2015, 04:16:09 PM
Is it feasible to build a separator to fit inside a 5 gallon bucket -- not a top hat design? I would like to build the smallest one possible. I assume that it would end up with less dust capacity but I can live with that.
Any comments welcomed!

Don, take a look here (http://woodgears.ca/dust_collector/cyclone.html) for a pretty small yet very effective 5gallon separator.

And at the bottom of that page, Look here for a CFD simulation of the 5-gallon bucket separator:

The images for "Clipped Internal Pressure Iso-Surfaces" and "Clipped Internal Velocity Iso-Surfaces" show a section of the outlet without a bell-mouth that are interesting.  You can also see the turbulent flow through the short radius 90° elbow in the outlet airstream in a many of the images. 

Perhaps the author could be persuaded to do other simulations.... ;)
