Lagrangian Micromixing Models for Concentration Fluctuations: An Overview

摘要: This study presents a brief overview of the main features, theoretical formulations and validation tests some Lagrangian micromixing models, currently used for estimations ensemble mean turbulent fluctuations concentration. Their application fields regards several pollutant dispersion phenomena such as: accidents (power or production plants, terroristic attacks, hydrocarbons storage transport, extraordinary emissions), odours plants energy from waste resources-compost, dumps, incinerators, biogas smokes-, high enthalpy geothermic plants-sulfide hydrogen-, animal farms), micro-scale continuous spot emissions (traffic pollutants, power in aquatic environments...), industrial processes (combustion, treatment,...), strong non-linear relationship between concentration damage (inflammable substances, explosions,..), reactions depending on instantaneous concentrations.
