Abstract
The paper presents some theoretical aspects regarding the upward velocity of particles in the cast aluminum - graphite composites. Many types of particles are used to analyze the influence of shape factor on upward velocity in aluminum melts. The calculations were made by using modified Stokes’ equation for different Reynolds number attached to graphite particles. At temperature 700-900°C the upward velocity increases about 8.5%. The viscosity of multiphase fluids depends on many factors such as: the properties of aluminum melt and complementary material; temperature of the metallic bath; concentration, shape, fineness of graphite particles and degree of agglomeration of the dispersed phase.
