Análise por métodos empíricos e DFC da eficiência de coleta de um separador ciclônico encontrado em uma indústria local

Abstract

This work aims to analyze the collection efficiency of a cyclone separator by empirical methods and CFD.A comparison between these methodologies will be made, in a specific cyclone separator found in a local industry, which presents a lower collection efficiency than expected. The specific cyclone has geometric dimensions that differs from the standard found in the literature, the application of CFD is a viable way to identify possible equipment operation problems, since empirical methods are limited to the limits of the experiments from which they were derived. The correct application of CFD can lead to a consistent prediction of the equipment's operation, in addition to allowing a resizing without the need for experimental tests. This work concludes that by means of empirical and CFD methods, this cyclone is in fact well designed for it’s defined application, where it can operate with 100% theoretical collection efficiency with particles that have at least 40 μm of diameter, therefore the possible reason of low efficiency by the equipment, is defined by a nonideal operation, as showed that geometric dimensions are well suited for the application.
