We consider a two‐phase Stefan problem for a semi‐infinite body

h>0 whose solution was given in D. A. Tarzia, PAMM. Proc. Appl. Math. Mech. 7, 1040307–1040308 (2007). We demonstrate that the solution to this problem converges to the solution to the analogous one with a temperature boundary condition when the heat transfer coefficient
h→+∞. Moreover, we analyze the dependence of the free boundary respecting to the jump density.

“…A majority of available studies refer to the onedimensional inverse Stefan problem (see [1][2][3][4][5][6], and references therein), whereas studies regarding the twodimensional inverse Stefan problem are scarce. The first study concerning the 2-D inverse design Stefan problem is Colton's work [7].…”
Section: Numerical Computation Of the Heat Transfer Coefficient In Thmentioning
This paper presents an example of the application of a genetic algorithm to a 2-D design problem, which consists in the reconstruction of the function that describes the convective heat transfer coefficient, when the position of the moving interface of the phase change is well-known. In numerical calculations the Tikhonov regularization, the genetic algorithm and the alternating phase truncation method were used. The featured examples of calculations show a very good approximation of the exact solution and the stability of the procedure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
