Analisi e sviluppo di modelli per la valutazione della dispersione di odori in contesti antropizzati

Lo scopo della tesi \ue8 quello di: (i) testare modelli numerici per la valutazione, previsione e controllo del livello di inquinamento olfattivo in aree urbane complesse, (ii) sviluppare algoritmi per la localizzazione di sorgenti odorigene sulla base di misure sparse e discontinue rilevabili da un sensore mobil

Urban air pollution by odor sources: Short time prediction

3noA numerical approach is proposed to predict the short time dispersion of odors in the urban environment. The model is based on (i) a three dimensional computational domain describing the urban topography at fine spatial scale (1 m) and on (ii) highly time resolved (1 min frequency) meteorological data used as in flow conditions. The time dependent, three dimensional wind velocity field is reconstructed in the Eulerian framework using a fast response finite volume solver of Navier-Stokes equations. Odor dispersion is calculated using a Lagrangian approach. An application of the model to the historic city of Verona (Italy) is presented. Results confirm that this type of odor dispersion simulations can be used (i) to assess the impact of odor emissions in urban areas and (ii) to evaluate the potential mitigation produced by odor abatement systems.openopenPettarin, Nicola; Campolo, Marina; Soldati, AlfredoPettarin, Nicola; Campolo, Marina; Soldati, Alfred
