I am a 5th year chemical engineering student at Universita' di Padova,

Italy, and I am working on experiments dealing with flows of powders.

I am looking for publications about velocity and stress distribution

for powders flowing down inclined chutes: can anybody help me?

Thanks for your answers!

Dear Mr. Castelli,

If possible please go through a book on Bins & bunker By Rothe & Genik. There you will find flow property & other related analysis. But you will not find any relation with CHUTE.

Flow Of Powders

Hi Alessandro,

If the powder behaves like a granular particle then normal flow equations apply. See

Conveyor Calculation http://www.cospire.com/browse.aspx?id=4317 Worksheet page on Chute Velocities.

See AW Roberts and OJ Scott "Flow of Bulk Solids through transfer chutes of variable geometry and profile" bulk solids handling Vol 1 No 4 Dec 1981. A lot of work has been done by the University of Newcastle. or TUNRA.

If your powder exhibits non-Newtonian characteristics, then you are into Flow-functions. The subject gets a lot more complex from there.
