On the contact heat transfer with melting. II - Analytical study
Abstract
The melting phenomena of a solid, pressed on a surface with the temperature higher than the melting point, were analyzed and calculated numerically. The analytical results concerning nondimensional heat flux agreed well with experimental results for water and octadecane shown previously. An approximate formula relating nondimensional heat flux with Stefan number and nondimensional contact pressure was proposed. The liquid layer thickness distribution between the heat transfer surface and the melting solid, besides the distributions of pressure, velocity and temperature within the liquid layer, was also calculated and discussed.
