Abstract
The purpose of this paper is to examine the effect of solutally induced flo w on segregation during a solidification process. An idealized horizontal B ridgman configuration with moving. planar solid-liquid interface has been n umerically simulated. Solutally induced flows are first described, before analysing axial and rad ial segregations. It is found that in the "convective" range, segregation r esults compare very well with power laws obtained in the frame of an order of magnitude analysis. (C) 2001 Elsevier Science B.V.
