The fluid dynamics and heat transfer behavior of a molten metal droplet freely falling on a substrate and melting the substrate is studied using combined analytical and numerical techniques in this thesis. The numerical evaluation of the remelting depth is the main objective of this study. This information can be directly used to select operating parameters in actual processes such as Microcasting shape deposition manufacturing and thermal spray deposition. A theoretical analysis of the solidification phenomenon is done using the Stefan solidification problem in which droplet and substrate are approximated as liquid and semi infinite solid regions. Theoretical analysis of this problem yields the range of initial temperatures that should be maintained in the solid and liquid regions to cause melting. Also a rough estimate of the melting depth can be determined from the analytical analysis. Further the variation of spread factor with respect to the Reynolds and Weber number has been studied using known formulations. (Abstract shortened by UMI.)Subjects--Topical Terms:
