Modelling research

The department has a long history of expertise in mathematical modelling of solid particle erosion and one of the most well known models developed in the 1960s -that of Neilson and Gilchrist-was the work of two former members of academic staff in the department, one of whom (Alistair Gilchrist) retired in 2001. This work continues today. Finite element models are being developed to predict the complex effects of component geometry on erosion in flowing conditions. Research is also being carried out on the development of predictive models of erosion/ wear in corrosive conditions to generate mechanistic maps of the process. These are important engineering tools which are designed to avoid the deleterious effects of tribo-corrosion. This group has established a lead in this area and is responsible for much of the recent developments in modelling and mapping of erosion-corrosion processes and have developed 2-D and 3-D maps for such processes.

mathematical models. Regimes of erosion-corrosion are based on the ratios of the

erosion to corrosion contributions.
