Abstract in Portuguese
Este trabalho apresenta uma extensão do ambiente de simulação Freeflow-2D para simulação de escoamentos incompressíveis com superfície livre e influência de temperatura. Dois modelos matemáticos foram analisados e implementados: o modelo de Boussinesq; e uma modificação no modelo proposto por V. Casulli (Casulli, 1980). As equações de conservação (momento, massa e energia) e as condições de fronteiras associadas são discretizadas utilizando diferenças finitas sobre malhas deslocadas. Resultados numéricos obtidos de simulações com os dois modelos são apresentados e discutidos.

Abstract in English
This work presents an extension of the Freeflow-2D environment to support simulation of incompressible non-isothermal free-surface flows. Two mathematical models were analysed and implemented: the Boussinesq approximation, and a modification in the model proposed by V. Casulli (Casulli, 1980). The conservation equation (momentum, mass and energy) and the associated boundary conditions are discretized using finite differences on staggered grids. Numerical results obtained from simulations with the two models are presented and discussed
