6 Conclusions

With the SPH method it is possible to obtain the Venturi effect in good agreement
with the experimental results. In the Venturi tube, the velocity increases as the pres-
sure difference increases. From the numerical results it was possible to obtain the
discharge coefficient as a function of the Reynolds number for Re

< 12,000.
