university of southern california Operations And Supply Chain Management Assignment Help - molten metal
Question - When a molten metal is cast in a mold that is a poor conductor, the dominant resistance to heat flow
is within the mold wall. Consider conditions for which a liquid metal is solidifying in a thick-waned mold
of thermal conductivity k... and thermal diffusivity an. The density and latent heat of fusion of the metal
are designated as p and hsf, respectively, and in both its molten and solid states the thermal
conductivity of the metal is very much larger than that of the mold.
Just before the start of solidification (S = 0) the mold wan is everywhere at an initial uniform
temperature T, and the molten metal is everywhere at its fusion (melting point) temperature of Tf'
Following the start of solidification, there is conduction ...Read More
