What is Effects of Rotation on a Nonaxisymmetric Chimney Convection During Alloy Solidification about?
Nonlinear buoyancy-driven convection in the melt and in cylindrical chimneys within a mushy layer during alloy solidi"cation is investigated under a high-gravity environment, where the rotation axis is inclined at an angle to the high-gravity vector. In the "nal form of the solidi"ed material these chimneys produce freckles, which are imperfections that reduce the quality of the solidi"ed material. Asymptotic and scaling analyses are applied to a nonaxisymmetric convection in the "nite Prandtl number (P P ) melt and in the chimneys. It is found that there are P P -and rotationdependent ranges where the wall of chimneys may or may not be vertical. There are also -, P P -and rotation-dependent ranges, where convection in the chimneys can increase or decrease with increasing rotation rate. The results are generally in agreement with available experimental observations.
