Subject aims expressed by acquired skills and competences

Students will learn about theoretical and practical approaches for the numerical solution of dispersion of pollutants in the atmosphere, through which they learn to design a mathematical model for solving the problem of this applications. An important part of the work is to evaluate solution, compare with theory and experiments and determine the limits of solvability in the field of application. This can give result in recommendations for the cases of emergency planning.

Summary

The course is theoretical and practical mastery of the numerical solution of dispersion of pollutants in the atmosphere possibly the spread of gaseous emissions from point, line or area sources. In doing so, may be counted relief terrain. If the student is familiar with basic aspects of thermodynamics and combustion, it is possible to solve problems of fire spreading and primarily solid combustible materials in the areas
