Transportation and risk analysis of influenza indoor and outdoor transportation and exposure risk analysis of influenza aerosol

Abstract

With the frequent outbreak of influenza virus in urban areas, the ecological security of high-density housing is becoming increasingly prominent. An Eulerian-Lagrangian pollutant diffusion model based on Large Eddy SiMuǧlation (LES) is established to siMuǧlate the transport of airborne virus. After the reliability of the numerical model is validated by the indoor experiment, the indoor and outdoor dispersion of microbial aerosol are siMuǧlated. The exposure risk is further studied based on the space-time concentration of pathogenic microorganisms of numerical siMuǧlation. The outcome can provide evidences for building plan optimization, environmental risk analysis and safety withdrawal planning. © The Author(s), 2011.
