As equações que governam o comportamento de materiais puros incluem a equação para o campo de fases, uma equação para a temperatura e uma equação singular do tipo de Navier- Stokes com um termo do tipo Carman-Kozeni e também um termo do tipo Boussinesq. Para ligas binárias, uma equação extra para a concentração do soluto _e incluída. Para materiais puros, tanto no caso bidimensional quanto no caso tridimensional, provamos a existência de soluções globais no tempo; no caso tridimensional, consideramos um modelo com dissipação mais intensa (não linear) do que no caso bidimensional. Para ligas binárias, obtivemos apenas a existência de soluções locais no tempo. Tais soluções são obtidas da seguinte forma: primeiramente o problema _e penalizado e uma sequência de soluções aproximadas _e obtida usando o teorema do ponto fixo de Leray- Schauder; então, usando argumentos de compacidade, provamos que esta sequência tem um ponto limite, o qual _e uma solução do problema original em um sentido generalizado. / Abstract: In this work we study four phase field models for the evolution of a solidification/liquefaction process of certain pure material or certain binary alloys, with the possibility of motion of the melt phase. The governing equations for pure materials include a phase-field equation, a heat equation and a singular Navier-Stokes system with a term of Carman-Kozeni type and a Boussines type term. For binary alloys, an extra equation for solute concentration is included. For pure materials, both in the two and three-dimensional cases we prove the existence of global in time solutions; in the three-dimensional, we consider a model with stronger (nonlinear) dissipation than in the two-dimensional case. For alloys, both in the two-dimensional and three-dimensional case, we obtain just local in time solutions. These solutions are obtained as follows: firstly the problem is penalized and a sequence of approximate solutions is obtained by using the Leray-Schauder's fixed point theorem; then, by using compactness arguments, we prove that this sequence has a limit point which is a solution of the original problem in a generalized sense. / Doutorado / Equações Diferenciais Parciais / Doutor em Matemática Solidificação Convecção (Meteorologia) Equações diferenciais parabólicas Solidification Convection (Meteorology)
