Microscopic study of coupled heat and mass transport during unidirectional solidification of binary solutions—I. thermal analysis - 29-38 p.

Coupled heat and mass transport phenomena occurring during the unidirectional solidification of a binary solution are studied utilizing a specially designed freezing stage for transmitted light microscopy. The apparatus provides the capability for real time direct observation of the freezing process along with simultaneous measurement of the time evolution of cellular-scale coupled concentration and temperature fields and their interaction. The experimental data provide a comprehensive specification of a freezing process at the microscopic level for use in developing models of the binary solidification process, including temporal and spatial temperature profiles, local rates of cooling and heat flux, and interface velocity and temperature.
