Other than text books, does anyone have knowledge of published papers dealing with this subject. Or better yet, if you could tell me what the heat transfer coefficient is for air flowing at 10 ft/min @ 50 degrees F through a bed of carbon where the voids are 40% and the mesh size is 4 x 10. The carbon could be 150 to 250 degrees F.

Heat transfer in packed bed of granules
- Thread starter gacguy
- Start date
I could find in books only the following formula for beds of uniform spherical particles:
Nu = 1.03 e(1.1-2.75p) Re0.6 +/- 8%.
Where,
p: void fraction;
Re is based on the air velocity for the empty cross-section and on the diameter of "spherical" particles D.
Sorry for not being of more help. Good luck !
