A unmarried connection with all features of up to date air dispersion modeling

The perform of air dispersion modeling has replaced dramatically in recent times, largely as a result of new EPA laws. present with the EPA's forty CFR half fifty one, this booklet serves as an entire connection with either the technological know-how and modern perform of air dispersion modeling. in the course of the e-book, writer Alex De Visscher publications readers via complicated calculations, equation by means of equation, assisting them comprehend accurately how air dispersion versions paintings, together with such well known versions because the EPA's AERMOD and CALPUFF.

Air Dispersion Modeling starts off with a primer that allows readers to speedy seize uncomplicated ideas via constructing their very own air dispersion version. subsequent, the booklet bargains every thing readers have to paintings with air dispersion versions and competently interpret their effects, together with:

  • Full bankruptcy devoted to the meteorological foundation of air dispersion
  • Examples in the course of the booklet illustrating how conception interprets into practice
  • Extensive discussions of Gaussian, Lagrangian, and Eulerian air dispersion modeling
  • Detailed descriptions of the AERMOD and CALPUFF version formulations

This e-book additionally comprises entry to an internet site with Microsoft® Excel and MATLAB® records that include examples of air dispersion version calculations. Readers can paintings with those examples to accomplish their very own calculations.

With its accomplished and updated assurance, Air Dispersion Modeling is suggested for environmental engineers and meteorologists who have to practice and evaluation environmental influence exams. The book's many examples and step by step directions additionally make it perfect as a textbook for college students within the fields of environmental engineering, meteorology, chemical engineering, and environmental sciences.Content:

Sample text

2 Gaussian Puff Models Gaussian puff models were designed to resolve the most glaring weaknesses of Gaussian plume models. They assume that the emission of a stack can be subdivided in a series of pollutant puffs that have a Gaussian concentration profile in all directions. Each puff follows the local wind speed and wind direction independently of other puffs. Hence, when the wind direction changes in space or time, the puff will follow a curved path. Puff models are more accurate than plume models.

3 Standard Conditions for Temperature and Pressure Stack gas emissions are often presented as volumetric flow rates at standard conditions of temperature and pressure (STP). Because stack gas can reasonably be assumed to be an ideal gas, the volume at standard conditions is an unambiguous measure of the amount of gas. Unfortunately, different standard conditions circulate in the technical literature, so the practice of defining standard conditions probably creates more ambiguity than it solves.
