Resumen:
The aim of this work is to simulate different length Borda Mouthpieces and to predict the
contraction coefficient of the jet for each case. In order to reach this objective initial simulations were
carried out of full original experimental device. This preliminary work allowed to isolate the orifice
zone without affecting the flow and concentrate computational efforts in orifice zone and capturing free
surface appropriately.
Volume of Fluid (VOF) Method was used to transport the free surface and sharpness was assured by
means of Geo Reconstruct scheme (implemented in FluentR code) and Interface Compression scheme
(implemented in OpenFOAMR code). Considerations on simulation such as mesh refinement, necessity
of turbulence modelling, influence of surface tension and boundary condition setting are discussed.
Finally, numerical results from both surface reconstruction schemes are compared with experimental
ones and good agreement is found. Additional validation is done against theoretical models found in
literature.R code) and Interface Compression scheme
