HERNANDEZ-RAMIREZ, Gabriel et al. Mathematical modeling of the load correction coefficient of the lateritic of hydromixtures pumping. Dyna rev.fac.nac.minas [online]. 2019, vol.86, n.208, pp.19-27. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v86n208.72006.

The purpose of the present research was to determine the correction coefficient behavior of the characteristics of the centrifugal pump load curves, using mathematical models, taking into account the rheological properties. From experimental studies such as X-ray diffraction, X-ray fluorescence, particle size analyzer, rheological analysis and mathematical modeling the behaviors of the physical and chemical interactions that take place in non-Newtonian fluids were obtain. It is concluded that to obtain a mathematical model of the correction coefficient and the equations describing the behavior of the characteristic load - discharge curves of the networks and of the pumps to, by means of the joint analysis of these, obtain the frequency of rotation of the impeller that guarantees the required flow rates in energy efficient operating regimes.

Palabras clave : mathematical models correction coefficient; centrifugal pump; non-newtonian fluids.
