Void fraction distribution in beds of spheres
Abstract
The radial variation of void fraction within a packed bed of uniform spheres has been found to vary from unity at the wall to about 38% in the interior of large beds. The voidage distribution takes the form of a damped oscillatory wave with the oscillations damped out at about 4½ to 5 sphere diameters from the container wall. The distribution function is essentially independent of whether the container wall is concave or convex. Continuous surfaces within the bed are responsible for local voidage variations similar to those at the container wall. An improved experimental technique is described in detail. The results presented are for a number of cases with D/d varying from 2.6 to infinity, and for boundary walls which are concave and convex.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
