EV4016 Air Quality Modelling Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
To introduce the theory of dispersion of air pollution in the atmosphere and major approaches for air pollution modelling and to demonstrate the features of most widely used commercial and freely available air quality models
UNIT I MODELLING AND MODELS
Overview of different types of models-deterministic and stochastic approach- steps in model development- numerical and simulations models- calibration and validation of models- limitations transport phenomena- mass balance analysis-model development and decision making. Types of air quality models-classification
UNIT II METEOROLOGY AND DISPERSION
Chemistry of air Pollutants – atmospheric reactions, sinks for air pollution –transport of air pollutants – meteorological factors for dispersal of air pollutants – meteorological modelling-developing wind rose and pollutant rose diagrams-vertical structure of temperature and stability, mixing height; tall stacks-transport and diffusion of stack emissions –plume segments–flare stack–plume rise equations-Holland’s and Brigg’s models.
UNIT III EMISSION AND SOURCE DISPERSION MODELS
Modeling for reactive and nonreactive pollutants, point source-single and multiple sources- area sources, line source models, fixed box models- diffusion models – Gaussian plume derivation modifications of Gaussian plume equation- Gaussian puff model- emission models-emission factors long term average-multiple cell model-accuracy and utilization-limitations-air quality mapping
UNIT IV RECEPTOR MODELS AND INDOOR AIR QUALITY MODELS
Receptor models- source apportionment studies- CMB model- PMF models; environmental wind tunnel models; indoor air pollutants –mass balance-single compartment-multiple compartments calculation of deposition velocity and Position of Particles-Aerosol-Odours and sick building syndrome-Integrated Models.
UNIT V SOFTWARE PACKAGE APPLICATIONS
Commercial air quality models – ADMS, AERMOD, CALINE, CALPUFF, DEGADIS, HYROAD, INDUSTRIAL SOURCE COMPLEX, SCREEN, HYSPLIT, INDEX
