Prediction of Air-borne Dust Concentration
(A.D.C.)in Woodworking Chamber
-Effect of Particle Shape on their falling
behavior and A.D.C.-
The distribution of air-borne dust concentration
in a model woodworking chamber caused by
fine particles in freefall was predicted
using a numerical method. The time change
of A.D.C. was analyzed taking the influence
of the complicated particle shape on their
falling behavior into account.

Relationship between
Heywood diameter
and Shape factors
The tempo of free fall depends
not only on the didameter but also
the shape of the particle. |
Simulated time changes of
airborne dust concentration in
comparison with measured value
A.D.C was simulated for different
equivalent particle diameter dk. |
