Abstract

In this study a thermal analysis is performed of the hot dip-coating process where solidification of metal occurs on a bar moving through a finite molten bath. Despite the importance of dip-coating as a modern manufacturing technology, no studies have been reported in the literature that have performed a detailed thermal analysis. A continuum model is considered in the present study where the important thermal effects such as axial diffusion, buoyancy, and shear induced motion are accounted for. Parametric effects of the bath geometry, and initial and boundary temperatures and solid velocity, as characterized by the Reynolds number, Grashof number, and Stefan numbers, are presented. Good agreement is obtained with available experimental results from literature.
