• Screening Efficiency an overview ScienceDirect Topics

    May 01, 2012· The influence of internal friction (b⁎) resulting from relative motion between the solid skeleton and the pore fluid is investigated in Figs. 5.1.4 and 5.1.5, by varying values of b⁎ (b⁎ = 0, 5, 50, and 500).Recalling b⁎ is inversely proportional to the permeability, it suggests that the material with b⁎ = 0 is the most permeable, and the material with b⁎ = 500 is the least

  • Improving the validity of wire screen unattached fraction

    Abstract. Wire screens are commonly used to estimate unattached Rn daughter fractions in ambient and mine atmospheres. However, it is now recognized that the unattached fraction is in reality an ultrafine cluster mode in the 0.5-3 nm size range and that the collection efficiency versus particle diameter characteristics of wire screens do not permit a distinct separation of the unattached and
