Resumo:
The growing concern with the environment, especially the adequate disposal of industrial effluents, has been attracting the attention of researchers and engineers that aim to minimize this problem and meet the requirements of environmental control agencies. The separation processes using ceramic membranes have stood out in this scenario as an important tool of treatment of contaminated water, due to their cost-benefit, long life and low energy consumption. In this sense, it was evaluated using the computational fluid dynamics (CFD), the thermal effect in the water / oil separation process via ceramic membrane. The series resistance model was adopted in conjunction with the conservation equations of mass, linear momentum and energy, which were solved using ANSYS CFX® 15. The numerical results show that the mathematical model used is able to predict the formation and growth of the boundary layer of concentration along the tubular membrane, as well as the permeation of the solute (oil) in the membrane.
