Zero kinetic undercooling limit in the supercooled Stefan problem

نویسندگان

چکیده

Nous étudions les solutions de la phase unique surfusion du problème Stefan, avec cinétique, qui décrit le gel d’un liquide en une dimension spatiale. En supposant que température initiale est entre point d’équilibre et invariante caractéristique dans liquide, notre théorème principal montre que, lorsque paramètre cinétique tend vers 0, frontière libre converge (éventuellement irrégulière) Stefan sans cinétique. L’unicité cette dernière a été montrée récemment (Delarue, Nadtochiy and Shkolnikov (2019), Ledger Søjmark (2018)). Les outils clés preuve sont formule Feynman–Kac, exprime à travers temps local processus réfléchi, un principe comparaison pour frontières libres différents paramètres

The Supercooled Stefan Problem in One Dimension

We study the 1D contracting Stefan problem with two moving boundaries that describes the freezing of a supercooled liquid. The problem is borderline ill–posed with a density in excess of unity indicative of the dividing line. We show that if the initial density, ρ0(x) does not exceed one and is not too close to one in the vicinity of the boundaries, then there is a unique solution for all times...

THE STEFAN PROBLEM WITH KINETIC FUNCTIONS AT THE FREE BOUNDARY

This paper considers a class of one-dimensional solidification problem in which kinetic undercooling is incorporated into the temperature condition at the interface. A model problem with nonlinear kinetic law is considered. The main result is an existence theorem. The mathematical effects of the kinetic term are discussed

Confluence of the nonlinear waves in the Stefan problem with undercooling

We assume that the Stefan problem with undercooling has a classical solution until the moment of contact of free boundaries and the free boundaries have continuous velocities until the moment of contact. Under these assumptions , we construct a smooth approximation of the global solution of the Stefan problem with undercooling, which, until the contact, gives the classical solution mentioned ab...

Morphological Instability of Similarity Solution to the Stefan Problem with Undercooling and Surface Tension

This paper concerns morphological stability of a similarity solution to the Stefan problem with surface tension and initial supercooling. The linear stability analysis shows that for a nonzero surface tension each perturbation mode with a nonzero wave number is stable. However, the solution is unstable with respect to perturbations with a zero wave number limit point in their Fourier spectrum. ...
