The method is immune to numerical diffusion problems that are a nuisance for typical simulation methods using a...

A mathematical model for the evaporation of a single droplet, subjected to convective drying in a spray dryer was developed to study the transient phenomena of particle formation. During the constant-rate drying period, the governing equations and boundary conditions were transformed into a form containing Peclet number, Pe, as the main controlling parameter. A numerical solution was developed ...

Abstract: as magnetic materials, semiconductors, pigments, catalysts, refractories and electronic ceramics. In this paper, wereported the preparation of NiAlThe resulting powder was chracterized by XRD, particle size analysis and SEM. The XRD patterns show that thecombustion technique was excellent to prepare single – phased cubic NiAlfound to be around 14 nm. From the particle size analysis, i...

Large systems of particles interacting pairwise in d dimensions give rise to extraordinarily rich patterns. These patterns generally occur in two types. On one hand, the particles may concentrate on a co-dimension one manifold such as a sphere (in 3D) or a ring (in 2D). Localized, space-filling, co-dimension zero patterns can occur as well. In this paper, we utilize a dynamical systems approach...

The manuscript presents results from measurements of new particle formation (NPF) in Beijing during Spring and Winter using high time resolution particle sizers. The characteristics of new particle formation at two adjacent sites were compared to assess the impacts of local traffic emissions on NPF. Traffic exhausts might emit primary particles or gas phase precursors that contribute significan...
