Vliv neizokinetického odběru na stanovení koncentrace prachu na prašné trati

Abstract

The master thesis deals with the numerical modeling of airflow and particle on a dirt track. The introduction describes the method of experimental measurement of the concentration particulate gravimetric method. In the work is defined mathematical model of flow in dirt track, which is located in the Energy Research center VSB – Technical University of Ostrava. The work includes the definition of a mathematical model and its application to an experimental device dirt track. The main contents of the thesis is to use a mathematical model of flow on a dirt track of Non-kinetic collection of solid particles in a pressure vacuum. In the last phase of diploma thesis is evaluation of flow field using a graphical display of basic variables (pressure and velocity), and the distribution of concentrations for mathematical modeling of the flow of dust particles of different sizes. The calculation model is formed as a 2D axially symmetric.
