Estimation of Fine Dust Particles Distribution in Machining Workshop Based on COwZ Model
COwZ model dry cutting fine dust particles dust emission
2011/8/4
Fine dust particles (diameter is less than 2.5 m) generated during machining processes, especially dry cutting, are harmful to operators, because they remain suspended in the air for long time...
Transport of dust particles from the Bodélé region to the monsoon layer – AMMA case study of the 9–14 June 2006 period

On saturation of betatron acceleration of dust particles behind shock fronts
betatron acceleration dust particles shock fronts
2010/3/9
Possible saturation of betatron acceleration of dust particles behind strong shock fronts from supernovae is considered. It is argued that the efficiency of the nonthermal dust destruction should be s...
Ice nucleation properties of mineral dust particles: determination of onset RHi, IN active fraction, nucleation time-lag, and the effect of active sites on contact angles

2010/1/18
A newly developed ice nucleation experimental set up was used to investigate the heterogeneous ice nucleation properties of three Saharan and one Spanish dust particle samples. It was observed that th...
Numerical simulations of the charging of dust particles by contact with hot plasmas
Numerical simulations dust particles hot plasmas
2009/11/3
Charging of individual dust particles in contact with hot plasmas is studied by numerical methods. The dust particle is treated as a rigid solid body, composed by either perfectly insulating or conduc...
