Abstract:
Erosion in industrial appliances causes huge loss of valuable resources especially when solid
particles are present in the working medium. A number of erosion models that are available in
the literature claimed to predict the erosion response. In this work, five erosion models have been
evaluated using computational fluid dynamics (CFD) methodology. Three most commonly used
experimental test rigs (solid particle and unsubmerged slurry jet type and pot type) have been
simulated and comparisons with the experimental results have been performed. The study helps
in understanding the effect of fluid medium and flow pattern on the erosion process. The
knowledge acquired shows that phenomenological based erosion models give better results
considering the wide range of operating parameters. The in-depth study of the flow field shows
the possibility that erosion mechanism, being parameter dependent, could change with location
on the same specimen.
