Abstract

A study related with the reological effects of the blood in an artificial kidney of parallel plates is presented in this article. Using a difussion model, the previous considerations and establishing the height and longitude of the channel, the volume and the surface area of the dialyzer were determined and compared the concentrations of the toxins in the plates. It was found that when the blood is considered as a non-newtonian fluid, a considerable decrease exists in toxins’ concentrations in comparison with the supposition of the newtonian fluid, taking the value of zero at a distance of 0.0025 m.
