Mesoscopic Modelling of Abrasion/Attrition in Particulate Solids
One of the undesirable transformations of a particle in processing and handling of bulk solids is attrition, i.e. wear and erosion of surface asperities and chipping. This phenomenon can cause loss of valuable material, change in the bulk solid properties, and hazardous conditions in which fines are suspended in the surrounding atmosphere.
The available models consider wear as result of propagation of sub-surface cracks formed in semi-brittle material failures or are simple models for ideal conditions. Therefore, there is a need to develop abrasion model by considering surface characteristics, material properties and environmental conditions. In this work, a numerical method based on Peridynamic approach (Silling 2000) will be developed for the first time that is capable of simulating deformation and fracturing of asperities in contact.
The project is in close collaboration with the Manufacturing Technology Centre (The MTC, www.the-mtc.org). The student will have an industrial supervisor and is expected to spend a secondment at The MTC. The student will also have access to a generous £8k research grant to cover costs, plus free access to the relevant facilities at the MTC to obtain experimental data for validation of the developed numerical models.
Applicants should hold, or expect to obtain a first class honours degree in relevant subject areas (e.g. Mechanical Engineering, Chemical Engineering, Applied Math or Physics), strong analytical skill and have some high performance computing (HPC) and programming experience (preferably in Fortran or C/C++).
Proposed Start Date: October 2019
This is a 3.5 year fully funded scholarship which covers Home/EU tuition fees, providing a tax free stipend of £15, 009 for 2019/20 (subject to increase).
Fees and stipend can be awarded to UK and EU students and not to EEA or International students. EU students are only eligible for stipend if they have been resident in UK for 3 years, including for study purposes, immediately prior to starting their PhD. If an EU student cannot fulfil this condition then they are eligible for a fees only studentship. International students can be funded if they are ‘settled’ in the UK.
