ONE-PHASE STEFAN PROBLEM WITH A LATENT HEAT

The heat, i.e. transfer of thermal energy, from the air outside is melting the ice. The thermal energy added is breaking the bonds between the ice molecules and water is forming. While

Stefan Problems for Melting Nanoscaled Particles QUT

where Q is the heat that is added, c is specific heat, m is mass and ?T is the change in temperature. The usual units used for quantities in this equation are degrees Celsius for temperature (sometimes Kelvin), grams for mass, and specific heat reported in calorie/gram °C, joule/gram °C, or joule/gram K.

HEAT AND MASS TRANSFER Solved Problems By Mr. P.

the classical Stefan problem, the latent heat is considered to depend inversely to the rate of change of the seepage front. In this paper, we study a one-phase Stefan problem with a latent heat that depends on the rate of change of the free boundary and on its position. The aim of this analysis is to extend prior results, nding an analytical solution that recovers, by specifying some

Chapter 19 First Law of Thermodynamics

A three-time level implicit scheme, which is unconditionally stable and convergent, is employed for the numerical solution of phase-change problems, on the basis of an analytical approach consisting in the approximation of the latent heat effect by a large heat capacity over a small temperature range.
