ANSYS® Fluent simulation of a conventional chimney

Abstract

The aim of this master final project is to simulate a conventional industrial chimney to know its internal dynamics. Two different models have been considered, one with a laminar regime and the other with a turbulent one. Two different simulations have been made in each model; one that only includes a mixture of gases as an inlet fluid and another that incorporates particles to the previous model. Firstly, the model has been validated based on the query of different sources. Once the model has converged, there have been studies of pressure, temperature and velocity. The dimensions of the chimney have been established based on current state regulations and are identical in both models. Moreover, in order to understand better the study, a detailed explanation of the different stages (model geometry, meshing and setup) was performed and the results are shown in images as contour, vectors and some graphics. The energy balance has also been squared and the hydrodynamic length has been calculated
