Neste contexto, o  nivel de realismo e o tempo de execuc'ao de uma simulac'ao estao intimamente relacionados com a precisao numerica da soluc'ao obtida e devem ser escolhidos de acordo com o tipo de aplicac'ao. Uma das estrategias mais populares para a realizac'ao da simulac'ao computacional do escoamento de um fluido e o metodo Smoothed Particles Hydrodynamics (SPH). O metodo trata o fluido como um conjunto de particulas e aproxima as grandezas fisicas atraves de calculos sobre particulas vizinhas. Este trabalho utiliza o metodo SPH para simular o escoamento de fluidos bifasicos atraves de meios porosos. Para isso, o dominio poroso e representado por um grid cujas celulas representam regioes solidas ou poros. O tratamento das condic'oes de contorno e realizado atraves do calculo de colisoes geometricas entre as particulas de fluido e a superficie das celulas solidas. Palavras-chave: meios porosos; fluidos bifasicos; Smoothed Particles Hydrodynamics; computac'ao grafica.

In this context, the  level of realism and runtime of a simulation are deeply related to the precision of the obtained numerical solution and must be chosen according to the application type. One of the most popular strategies for the computational simulation of fluid flows is the Smoothed Particles Hy- drodynamics (SPH) method. It treats the fluid as a set of particles and approximates physical quantities through calculations over neighbor particles. This work uses the SPH method to simulate the flow of biphasic fluids through porous media. To achieve that, the porous domain is represented by a grid whose cells represent either solid regions or pores. The treatment of boundary conditions is made through the computation of geometric collisions between the particles of the fluid and the surface of the solid cells. Keywords: porous media; biphasic fluids; Smoothed Particles Hydrodynamics; computer graphics. 8P:p'.
