CFD study of Jet Impingement Test erosion using Ansys Fluent R
And OpenFOAM
a b s t r a c t
The initial aim of this study was to compare OpenFoam and Ansys Fluent in order to verify OpenFoam’s
Lagrangian Library and erosion capabilities. However, it was found that previous versions of Fluent
have been providing wrong results for the discrete phase and the differences with the latest version
(Ansys Fluent 15) are shown. A Submerged Jet Impingement Test is an effective method for studying
erosion created by solid particles entrained in a liquid. When considering low particle concentrations
a Lagrangian modeling of the particulate phase is a reasonable approach. Proper linkage between
OpenFOAM’s Lagrangian library and the solver pimpleFoam for incompressible transient flows allows
two-phase simulations to be undertaken for comparison with Ansys Fluent with the aim of verifying
OpenFoam’s accuracy. Steady state convergence for the fluid flow is first accomplished and the results
are compared, confirming a good agreement between the two packages. A transient simulation was
then set up and spherical particles incorporated into the fluid flow. An assessment of the two codes’
