Title: Inlet Design
Post by: Mainebarn on January 27, 2016, 09:09:37 AM
Hello,

I was planning to make a traditional Thien baffle (inside the can--not a top hat design).  I see the inlet tube is often partially cut away so it can be moved closer to the side or pointed more towards the side of the can.  I was thinking maybe tapering the end end of the tube instead (like my drawing attached).  Just curious what your thoughts on this would be?  Would it help shape the airflow towards the side of the can or would it be restrictive or detrimental to the air flow?

Thanks

Only speaking off the top of my head but I would not reduce the diameter of the tube.  Instead I would try Making the end retangular so as to have the same area at the outlet.  Just shooting from the hip.  I made mine like your 1st picture cutting off the edge.  I would fefinitely like to see any results from testing on that idea.

Thanks.  That was my thinking also.  I drew another with a rectangular outlet--making sure the area was at least as large as the round portion.

Great, that should work better than reducing the diameter (area) of the pipe.
