“…For this case, all predicted results were validated with the results reported by Damak and co-authors [23][24][25]. This information can be verified by the good agreement between the data, as shown in previous work [9]. It is expected that the number of elements in the 3D mesh would be higher than that used in this work.…”

“…where T is the temperature in Kelvin, and the terms A, B, C, and D are the regression coefficients, as shown in Table 4. The model validation was realized in a previous work [9], by comparing the numerical results obtained in the simulations with the data available in some works reported in the literature [23][24][25][26]31].…”

“…Simulations were performed, by using different fluid inlet temperatures, and the other parameters were kept constant; these values were adopted based on the work developed by Magalhães et al [9], Damak et al [23], and Magalhães et al [32]. Table 5 presents information about the parameters used in the simulations, and Table 6 shows all the cases studied.…”

Currently, the oil industry deals with the challenge of produced-water proper disposal, and the membrane-separation technology appears as an important tool on the treatment of these waters. In this sense, this work developed a mathematical model for simulating the oil/water separation by a ceramic membrane. The aim was to investigate the thermal aspects of the separation process via computational fluid dynamic, using the Ansys CFX® 15 software (15, Ansys, Inc., Canonsburg, PA, USA). Oil concentration, pressure, and velocity distributions, as well as permeation velocity, are presented and analyzed. It was verified that the mathematical model was capable of accurately representing the studied phenomena and that temperature strongly influences the flow behavior.

“…Besides, solute accumulation at interface membrane/solution is inevitable. Because of the importance, several studies involving the membrane separation process with computer codes' aid based on CFD tools (Computational Fluid Dynamics) have been conducted, for example, Porciúncula [9], Vieira et al [13], Souza [14], Cunha [15], Cunha et al [16], Cunha et al [17], Magalhães et al [18], Souza et al [19], Magalhães et al [20], Oliveira [21] and Magalhães et al [22].…”

One of the main challenges related to the oil industry is the conscious disposal of effluents from the stages of oil exploration and production. The treatment of the water produced originated these processes has become a challenge for the sector. The membrane filtration technique emerges as an important tool in the treatment of these oily waters, due to their good characteristics, such as uniformity in permeate quality and long shelf life. In this work, a 2D mathematical model was developed, using computational fluid dynamics (CFD) as tool for the evaluation of the water-oil separation process in a tubular ceramic membrane. Linear momentum, energy, and mass conservation equations were used, which were solved using the commercial package ANSYS CFX® 15. The results obtained demonstrate that the developed model was able to predict the behavior of the water/oil separation process through the membrane, evidencing the influence of the oil particle size under the formation of the polarization layer by concentration, as well as, allowed to verify the importance of the temperature and the retention index of the solute under the permeation velocity and system performance.
