Environmental Pollution, Real Time Prediction of Impact
Emissions from industrial activities often generate discomfort and health risks. In addition to the regulatory methods which can be used by the 3D softwarefluidyn-PANIEA (industrial impact on air quality, odour…), operational and communicative methods can be carried out with the help of the 3D CFD software platform fluidyn-PANACHE :
Operational Method : In order to allow the site operators forecasting impact of their activities and adapt operations on site, a real time dispersion simulation model has been developed. Emission estimation can directly be obtained from real time data coming from site measurements (pollutant concentration, wind). Instantaneous meteorological condition also coming form site measurement can be reproduced thanks to representative pre calculated wind field data base of the site. Use of the integrated Lagrangian puff model allows real time production of dispersion cartography (pollutant concentration / odour).
Communicative method: Based on weather prediction and site operations planning, dispersion prediction (pollutant concentration / odour) can be performed several days in advance. Combination of pre calculated wind field data base of the site and Lagrangian puff model leads to fast calculation. Cartography obtained through this methodology allows communicating with neighborhood about olfactory discomfort prediction several days in advance thanks to website, mass mailing.
