Abstract This paper is devoted to direct numerical simulation of the fluid flow and macrosegregation in horizontal Bridgman systems. Results concerning the fluid flows at Pr=0 and Pr=0.015 are given for various values of Gr and in situation where the melt-crystal interface is at rest. Practical laws concerning the behaviour of the mass transport and the level of inhomogeneity in the cavity are derived. The effects of some parameters such as Gr, Sc and the pulling speed on the concentration repartition in the two phases melt and crystal are studied and the average concentration in the crystal is shown for various situations.
