Das boundary problem
In mathematics and its applications, particularly to phase transitions in matter, a Stefan problem is a particular kind of boundary value problem for a system of partial differential equations (PDE), in which the boundary between the phases can move with time. The classical Stefan problem aims to … See more The problem is named after Josef Stefan (Jožef Stefan), the Slovenian physicist who introduced the general class of such problems around 1890 in a series of four papers concerning the freezing of the ground and the … See more The one-dimensional one-phase Stefan problem The one-phase Stefan problem is based on an assumption that one of the material phases may be neglected. Typically this is achieved by assuming that a phase is at the phase change … See more • Free boundary problem • Olga Oleinik • Shoshana Kamin • Stefan's equation See more From a mathematical point of view, the phases are merely regions in which the solutions of the underlying PDE are continuous and differentiable up to the order of the PDE. In physical problems such solutions represent properties of the medium for each … See more Apart from modelling melting of solids, Stefan problem is also used as a model for the asymptotic behaviour (in time) of more complex problems. For example, Pego uses matched … See more The classical Stefan problem deals with stationary materials with constant thermophysical properties (usually irrespective of phase), a constant phase change … See more 1. ^ Applied partial differential equations.

The results were unpredictable variations in ROP, WOB and drilling processes that could not be repeated from well to well.
