Mathematical modeling of the coefficient of load correction of the pumping of hydromixtures lateritic
Abstract
The purpose of the present investigation was to determine the behavior correction coefficient 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 we obtain the behaviors of the physical and chemical interactions that take place in non-Newtonian fluids. 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.
