This problem relates to the production of chips in a particular process. A potato composite composed of multiple mashed ingredients and small particles is fed through a spreading manifold. This forces the mash into a cylindrical mould (forming process) on a rotating drum to produce mouth sized disk pieces, which then continue to a drying process. During the forming process a scraper is used across the top of th...
This report concerns a forming process in which mash is forced from a spreading manifold into moulds on a rotating drum, transported in the moulds underneath a surface held flush with the drum (the shoe), and ejected from the moulds. The quality of the final product is understood to be related to the shear stresses experienced by the mash in the moulds as it is transported under the shoe. We describe and analys...
Expressing the properties of the exit material as a function of the potential difference and mass flux (scraping rate) and solving the mechanical problem in order to obtain a velocity field to be fed into multi-physics numerical platforms.; Dept.

The study group was tasked to investigate: 1. how gas ows through irregularly shaped particles, and whether the Kozeny-Carman equation (relating the Kozeny-Carman constant K, porosity \phi and specific surface area S_k), could be improved to extend the usual spherical particle geometries to account for cylindrical, tetrahedral, ellipsoid and rhombic particle geometries; 2. the critical pressure for the collapse...
The Atomic Weapons Establishment is interested in the behaviour of highly reactive chemical beds, in order to produce more reliable explosives. To improve understanding of the reaction evolution and bed mechanics the study group investigated the experiments of Goveas (1997), which involved the reaction of small beds of potassium picrate particles. The study group developed a mechanistic model and used simplifie...
