The slip correction factor has been investigated at reduced pressures and high Knudsen number using polystyrene latex (PSL) particles and the major sources of uncertainty are the diameter of particles, the geometric constant associated with NDMA, and the voltage.
Comparisons of the soot volume fraction using gravimetric and light extinction techniques
Structural analysis of soot agglomerates
Etude de la structure des agglomerats de noir de carbone formes par combustion d'acetylene dans un bruleur a diffusion coannulaire
Comparison of a fractal smoke optics model with light extinction measurements
Specific extinction coefficient of flame generated smoke
The experimental results for the mass specific extinction coefficient (σs) at λ=633 nm for flame generated smoke are summarized for seven studies involving 29 fuels. The measurements are for…

On Two Numerical Techniques for Light Scattering by Dielectric Agglomerated Structures
The effects of the finite size of the primary spheres have been numerically delineated and the two methods obtained in this tutorial paper directly from the monochromatic Maxwell curl equations have been equivalent.
Generation and Transport of Smoke Components
Smoke is a mixture of gases, vapors, and suspended particulate matter, or aerosols. The nature of the aerosol component of smoke can play a significant role in its deposition in the fire environment…
