Measurements of ultrafine particle concentration and size

Sep 01, 1999· For most of the time, particles larger than 72 nm (50% cut size) remained almost steady at approximately 3.5×10 4 particle cm −3, and total particle number concentration variation measured by the ELPI was dominated by ultrafine particles (30–72 nm, 50% cut size), with an average of 8.2×10 4 particle cm −3. Traffic emission is the source of these ultrafine particles.

The effect of particle properties and solids concentration

May 01, 2020· The yield stress increases with increasing solids volume fraction for both ultra-fine calcium carbonate and barite samples. Calcium carbonate samples were stronger than the barite equivalents with yield stresses showing an increase of between 29% and 56%. However, broadening the particle size distribution in the cake tended to give stronger

Experimental investigation of ultra-fine particle size

This research revealed an essential change in the size distribution of fine and ultra-fine particles during their transport from the road. A conclusion has been drawn that both coagulation of particles and turbulent dispersion contribute to the rapid decrease in particle number concentration (Zhu et al, 2002a).
