It needs a correction applied when the aerosol is not in the continuum regime.\nCorrected concentration above particle surface\nThe saturation concentration is found and then it is corrected for the curvature (Kelvin) effect and solute (Raoult) effect.\n\n\nTime Loop\nEstimate of concentration change based on difference between bulk vapour-phase concentration and concentration above particle surface, following Ficks first law (eq. 3 of Zaveri et al. 2008).  This is the governing equation for partitioning.\n\nThe code includes an option to use the partitioning equation with the effect of partitioning on particle radius through the mass transfer rate and the curvature effect accounted for.  There is also an option where the effect of partitioning on radius is presumed to be relatively small and so mass transfer rate and curvature effects are assumed constant.\n\nOutput\nMass fraction remaining in particle phase\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsimonom%2Fdilu_cham_modl","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsimonom%2Fdilu_cham_modl","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsimonom%2Fdilu_cham_modl/lists"}
