Desenvolvimento da técnica PLIC-VOF no sistema HiG-Flow para simulação de escoamentos bifásicos

Abstract

The purpose of this master thesis was to study and implement numerical techniques for the computational simulation of incompressible, immiscible and isothermal two-phase flows of Newtonian fluids. In two-phase flows, a consistent description of the interface between fluids is very important to ensure accurate numerical simulation. The volume of fluid (VOF) method was used to locate and reconstruct the interface. The continuum interfacial force (CSF) model was considered for the balance of forces at the interface. Navier-Stokes equations were solved using the HiG-Flow solver, in which the VOF method was coupled. For the analysis of numerical results, the implemented methods were verified using data and classical problems of the literature, and proved to be consistent.
