The purpose of the work has been the evaluation of flow and solidification of AlMg10 alloy during the fill mould cavity in the spiral fluidity test and simulation of graphite particles movement during the filling of mould cavity the composite suspension on AlMg10 alloy matrix. This evaluation has been performed on the basis of computer simulation of the mould cavity filling and the solidification of the casts using by means of the Nova Flow and Solid program. The AlMg10 alloy has been cast into the oil sand mould. During the simulation changes of temperature have been registered, the solid phase fraction growth has been observed, and the changes of flow rate in the mould channel have been recorded until the flow stop. A series of figures presents the arrangement of the graphite particles during the subsequent flow stages and after the flow stop. This distribution of graphite particles has been compared with the results of particle trajectory calculations obtained from the solution of the flow equation showed in earlier publications.Keywords: Composite, graphite particle, aluminum alloy, simulation, solidification
