EN3011 Air Quality Modeling and Mapping Syllabus:
EN3011 Air Quality Modeling and Mapping Syllabus – Anna University Regulation 2021
COURSE OBJECTIVES:
To introduce the fundamentals of air pollution with a background on historical perspective on air pollution.
To introduce the theory of dispersion of air pollution in the atmosphere.
To discuss the major approaches for air pollution modeling
To demonstrate the features and the use of most widely used commercial and freely available air quality models
UNIT I MODELING CONCEPT
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.
UNIT II AIR POLLUTION MODELING
Chemistry of air Pollutants – Atmospheric reactions, sinks for air pollution –Transport of air Pollutants – Meteorological settling for dispersal of air pollutants – Vertical structure of temperature and stability, atmospheric motions, Wind and shear, self-cleaning of atmosphere; transport and diffusion of stack emissions – atmospheric characteristics significant to transport and diffusion of stack emission – stack
UNIT III AIR QUALITY MODELS
Types modeling technique, modeling for nonreactive pollutants, single source, short term impact, multiple sources and area sources, Fixed box models- diffusion models – Gaussian plume derivation- modifications of Gaussian plume equation- long term average-multiple cell model- receptor oriented and source oriented air pollution models- model performance, accuracy and utilization-air Quality Index -air quality mapping
UNIT IV INDOOR AIR QUALITY MODELS
Indoor Air Pollutants – Volatile Organic Compounds , Inorganic Gaseous Pollutants Respirable Particulates ,Bioaerosols, Radon and its decay products-Infectious disease transmission- A/C units in indoor- Odours and sick building syndrome-Indoor Air quality Models.
