ABSTRACT
The results of the fluidity test obtained by computer simulations (software NovaFlow&Solid) and by experiment were compared. Two types of the molds were used: a horizontal mold with 3 canals and a vertical mold with 6 risers. AlSi10MgMn (EN 1706) alloy was the experimental material, the casting temperatures ranged between 605°C and 830°C in ten levels. Measurement systems analysis (MSA), the analysis of the variance (ANOVA), t-test and the analysis of correlation were used for the evaluation. Values of fluidity for each temperature level obtained by the horizontal mold have a high degree of agreement with those obtained by casting process simulation. On the contrary, the values, obtained by the vertical mold are more sensitive to the operator. This fact caused the match between the simulation and a practical experiment is only partial.

Keywords: fluidity, test, Al-Si, computer simulation.
