Reduction of Particle Reentrainment Using Porous Fence in Front of Dust Samples
Wind tunnel experiments were conducted to measure the emission factor of particle reentrainment from a dust sample with or without a porous fence. The effect of wind velocity, fence porosity, and distance between the fence and the dust sample on the emission factor was studied. A 20% porous fence wa...

| Zusammenfassung: | Wind tunnel experiments were conducted to measure the emission factor of particle reentrainment from a dust sample with or without a porous fence. The effect of wind velocity, fence porosity, and distance between the fence and the dust sample on the emission factor was studied. A 20% porous fence was found to be effective for reducing the particle reentrainment at a low wind velocity of
5
m∕s
. When the wind velocity was increase from 7 to
15
m∕s
, the results show that the particle reentrainment can also be reduced in a certain region behind the fence (
