Um bombeamento hidráulico não convencional: elevador Cherepnov.

Abstract

This work is about the study of an alternative device for water elevation, which does not need any kind of fitei or electric energy. The device studied was the Cherepnov water lifter, which had its origin in Rússia in 1962. The lifter proposed by the Russians was studied by American engineers. It had automatic controllers that needed some kind of energy not available in the water flow. The flow from the lifter is described by means ofa large quantity of equations of high complexity. In this study, modifications were made in the lifter to automatize the cycles using only the water and the energy available in the flow. These modifications changed the equation of the lifter's flow, this way, increasing more and more the number of equations and their complexity, since each stage was theoretically described rigorously. To describe all the cycle of the lifter equilibrium operation, a total number of 93 algebraic and differential equations were necessary. To resolve all of these equations computer program was elaborated. In order to adjuste and to validate the theoretical model a physicalmodel was built in some of the Centro Tecnológico de Hidráulica's rooms. After the validation of the theoretical model the flows were simulated to study several aspects of the lifter.
