| Popis: | This work aims at validating and extending the applicability of an existing correlating equation for predicting pressure drop through packed beds of spheres. A new set of data points out its use for bed geometric aspect ratio D / d part in the range 3.8–14.5, in the case of dense packings. The case of loose packings is also discussed using literature data. As a conclusion, a correlation is proposed for predicting pressure drops through fixed beds of spheres (dense and loose packings) for large ranges of Reynolds numbers (∼10 Re part D / d part |
