- Abstract
- A very large number of papers have been published on erosion for over 50 years. For thefirst time, a series of geometry independent tools and methodologies have been developed to calculate erosion and its associated mesh deformation in any three dimensionaldomain. The software used for development is verified first against the literature andAnsys Fluent. An error was found in the implementation of the Lagrangian phase inFluent which was corrected in a later version. It is suspected that the error affects alarge number of CFD publications in which the Discrete Phase Model was used. Anexperimental methodology and test-rig that is able to erode samples at mass concentrations ranging from 1% to 7% were developed and repeatability confirmed throughtesting. Despite not being able to use the test-rig due to technical issues, erosion associated deformation was validated from the literature, confirming the appearance ofa new stagnation area as the wear scar deepens in the Jet Impingement Test. Thealgorithm was also applied to centrifugal slurry pumps in combination with state ofthe art erosion modeling and its results validated through visual inspection of erodedmodels.
