Abstract
A bespoke 0.068m3 (18.5 gallon) sand hopper is employed at the newly established 50gTon centrifuge facility at the University of Sheffield. The sand hopper employs a series of mesh inserts of different diameters which control the flow rate and thus the relative density of the model. A series of calibration tests on equivalent Fraction E and Fraction C sands were performed to calibrate the mesh diameter and drop height for a desired relative density. Result showed that the sand hopper is capable of delivering repeatable relative densities in the range of 30% to above 90%, for both kinds of sand grades. This wide range relative density is considered sufficient to satisfy the needs of researchers preparing dry sand models for testing in the center.
