Question: Estimate the temperature gradient to be maintained within solid aluminum so that the planar solidification front moves into liquid aluminum maintained at its melting point

Estimate the temperature gradient to be maintained within solid aluminum so that the planar solidification front moves into liquid aluminum maintained at its melting point at a velocity of 0.5mm/s. For Al: Thermal conductivity =225W/mK, latent heat of fusion =398kJ/kg, density =2700kg/m3,Tmelting=660.4C
