dc.description.abstractWind 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 (x/H<4, x=distance between fence and sample; H=fence height) for the 20% porous fence. A linear multivariable regression model was fitted to the logarithmically transformed experimental data. The good fit of the regression model makes it possible to estimate emission rate as a function of the dimensionless distance (x/H), the wind velocity, and the elapsed time.en_US
