Particle-Laden Multiphase Flows: A Finite Element Analysis on Biofuel Particle Emissions

Abstract

Particle-laden multiphase flow is an important subject of study in fluid mechanics, especially in the oil and gas industry. In this work, the particle emission from biofuel production is analyzed and simulated, 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 directly 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 simulator is built by means of The Finite Element Method (FEM) and the results are generated for different meshes, which are made for different geometries. All the results and comparisons are shown and discussed throughout this article.
