On entropy generation in phase-change heat conduction Academic Article uri icon

abstract

  • This paper addresses the entropy production in heat conduction, accompanied by melting/solidification. The expressions for the time derivative of the entropy and the excess entropy production in selected Stefan problems are derived. These physical quantities are shown to be meaningful evolution characteristics for several phase‐change processes that evolve towards equilibrium or self‐similar asymptotic attractors. Prigogine’s theorem of minimal steady‐state entropy production is shown to be invalid for the phase‐change heat conduction.
