Abstract
Particle-laden multiphase flow is an important subject of study in fluid mechanics. In this work, the particle emission from biofuel production and storage is analyzed and simulated, with respect to the different geometries associated with the fluid dynamics and dispersion of said pollutants, in order to obtain the main effects of such transportation into the atmosphere, that may cause environmental and health damages. The continuous phase is numerically simulated through the Navier-Stokes equations, for which the results are in complete accordance to the ones presented in the literature. As for the solid dispersion, an Euler-Lagrange analysis is made, which provides a better understanding of each particle trajectory. A numerical and optimized simulator is completely built by means of the Finite Element Method (FEM) and the results are obtained for different geometries. A validation of the model is first made with a classical fluid mechanics problem: the lid driven cavity, for both quadratic and MINI interpolations. A second domain is simulated to analyze particles' interaction with a fluid expansion and also with heat transfer is introduced to the problem. All the results and comparisons are shown and discussed throughout this document.
