A diffusion-induced transition in the phase separation of binary fluid mixtures subjected to a temperature ramp
diffusion-induced transition binary fluid mixtures temperature ramp
2011/8/16
Abstract: Demixing of binary fluids subjected to slow temperature ramps shows repeated waves of nucleation which arise as a consequence of the competition between generation of supersaturation by the ...

To elaborate stratospheric ozone depletion processes, measurements of diffusion coefficients of selected gas phase molecules (i.e. HCl, CH3OH, HCOOH and CH3COOH; Katsambas et al., 1997; Kondratyev and...
Effects of resolution on the relative importance of numerical and physical horizontal diffusion in atmospheric composition modelling
numerical and physical horizontal diffusion atmospheric composition modelling
2010/8/12
Numerical diffusion induced by advection has a large influence on concentration of substances in atmospheric composition models. At coarse resolution numerical effects dominate, whereas at increasing ...
Evaluation of archived and off-line diagnosed vertical diffusion coefficients from ERA-40 with 222Rn simulations
diffusion coefficients ERA-40 222Rn

Boundary layer turbulence has a profound influence on the distribution of tracers with sources or sinks at the surface. The 40-year ERA-40 meteorological data set of the European Centre for Medium-ran...
Behaviour of tracer diffusion in simple atmospheric boundary layer models
tracer diffusion atmospheric boundary layer models
2008/12/22
1-D profiles and time series from an idealised atmospheric boundary layer model are presented, which show agreement with boundary layer measurements of polar NOx. Diffusion models are increasingly bei...
