Stefan problem

A problem that arises when studying physical processes related to phase transformation of matter. The simplest two-phase Stefan problem is formulated in thermo-physical terms as follows ([1], [2]): Find the distribution of the temperature and the law of motion of the dividing boundary (for example, the boundary "ice-water" in freezing water) from the equation of heat conductivity:

with the boundary condition

the initial condition

and the conditions on the freezing boundary

where and are the coefficients of heat conductivity, and are the specific heats, and are the densities of the solid and the corresponding liquid phase, is the latent heat of melting per unit of mass, and is the temperature of freezing. This problem has a self-similar solution , , .

A sufficiently-general formulation of the Stefan problem in the three-dimensional spatial case reduces to a boundary value problem for a quasi-linear parabolic equation of the second order with piecewise-continuous coefficients having discontinuities of the first kind on previously-unknown but sought-for surfaces, on which the value of the required function is defined, and which also satisfy the differential Stefan condition. The existence and uniqueness of classical and generalized solutions of the Stefan problem have been studied ([3]–[6]); for methods of approximate solution of the Stefan problem, see [2], [4], [6].

One of the first to study this type of problem was J. Stefan [1].

Comments

The problem was formulated by Stefan in [1] and [a1], but it was first studied many years before by G. Lamé and B.D. Clapeyron in a joint paper [a2].

The mathematical theory of the classical Stefan problem in one space dimension has been developed between 1947 and 1967 mainly by L. Rubinstein (see [a3]), A. Friedman (see [a4]), Jiang Li-shang, J.R. Cannon and C.D. Hill (see [a5]).

Other fundamental papers on the generalized solution of the Stefan problem are [a6]–[a8]. The reduction to a variational inequality has also received great attention [a9], [a10].

In the 1970's and 1980's many generalizations have been studied, not only concerning the conditions on the free boundary or the differential equation (see Stefan condition), but also considering the possibility of supercooling or superheating phenomena, possibly producing singularities of the solution (see e.g. [a11]–[a13]) or the occurrence of regions (called mushy regions) where the temperature is equal to the melting temperature and in which the thermal energy (or, more precisely, the enthalpy) satisfies a hyperbolic equation (see [a14]–[a16]).

Important references are also the survey papers [a17] (general theory), [a18]–[a19] (numerical methods).

The Stefan problem is related to many other free boundary problems, like the problem of gas flow through porous media (see [a20]). A useful guide to the extensive literature on the Stefan problem is [a21].
