A two-dimensional optical technique has been developed to measure absolute soot volume fractions, particle number densities, and mean particle radii in moderately sooting laminar and turbulent diffusion flames. The RAYLIX technique is based on the two-dimensional detection of Rayleigh scattering and the laser-induced incandescence (LII) signal in ...

Abstract Particle number emission factors, and the volatility of the particles, are measured on-road for five gasoline direct injection vehicles over a wide range of operating conditions including urban and highway driving conditions. Two condensation particle counters (CPC) were used to measure nascent and non-volatile (thermodenuded) particle ...

Abstract Background Few studies have investigated respiratory effects of particulate matter air pollution using a full range of particle size distribution. Objectives To explore the short-term associations between size-fractionated particle number concentration (PNC) and chronic obstructive pulmonary disease (COPD) mortality.

Abstract The accurate prediction of the drag force exerted by a fluid on assemblies of particles is critical to simulate key characteristics of gas-solid systems such as the bed expansion in fluidized beds. To this end, a lattice Boltzmann method has been applied to compute the drag force acting on assemblies of cubes for a wide range of Reynolds ...

Abstract The natural spin orbital (NSO) representation of the single-density configuration interaction (SDCI) is an infinite set of partially occupied one-particle states. The occupation probabilities are related to the CI expansion coefficients. The correlation one-density, the difference between the Hartree–Fock (HF) and CI one-densities, with the ...
