“…For this research, crude oil from northern Mexico (viscosity at 298 K is 35000 mPa•s, API at 288 K is 10.2, SARA fractions (%) 39.6, 10.1, 23.5, and 26 11,27,30 was used. The solid phase was obtained from a mixture of sand (#20 mesh) and clay (5, 10, and 15 %) homogenized with deionized water (proportion 1:10 for clay content), compacted at 15000 psi (1 min).…”

In this work, the effect of distilled water, a biodiesel viscosity reducer, and a commercial nonionic surfactant on the apparent permeability of clay-sand cores through the analysis of contact angle, linear swelling, and porous media fluid flow for a northern Mexico crude oil was evaluated. The results showed that the clay content influences the contact angle values having a lower wettability effect in the rocky medium. The addition of biodiesel produces a fluid movement similar to the addition of distilled water. Biodiesel-based flow enhancer not only reduces the crude oil viscosity but also improves the flowability through porous media. However, this behavior is only valid if the soil is not saturated with salty water.

Symmetries in porous flows: recursive solutions of the Brinkman equation in polygonal ducts

In this paper, we solve the Brinkman equation for unidirectional, steady, incompressible and Newtonian flow through a duct of uniform cross-section in the shape of a regular N-gon under no-slip boundary condition on the surface of the duct in the absence of applied forces. We calculate solutions for small values of N and by analysing them we devise a recursive scheme of generating solutions for all N ≥ 3 . We obtain approximate expressions for the vortex lines for all values of N by applying a trigonometric perturbation on circular vortex lines and graphically compare them with exact vortex lines. We also graphically compare both exact and approximate vortex lines with Schwarz-Christoffel transformation.
