Programa computacional para simulação do rendimento de ejetores para fins de dragagem

Abstract

A computer program was developed in this research to predict and evaluate the performance of ejectors for pumping of mixtures of water and solids in suspension in the mining activities. The structure of the program consists in inputting data points from characteristic curves obtained with the ejector operating with water both as driving and suction fluid, supplied by the manufacturer, for calibration of the head loss coefficients and simulation of the ejector performance for different flowrates, specific mass and concentration by weight of the solids in the suction fluid, based on the conservation equations for mass, momentum and energy. The results obtained with the program presented good agreement with experimental data available in the literature.
