The similarity method and explicit solutions for the fractional space one-phase Stefan problems

Abstract

In this paper we obtain self-similarity solutions for a one-phase one-dimensional fractional space one-phase Stefan problem in terms of the three parametric Mittag-Leffer function $E_{\alpha ,m;l}(z)$. We consider Dirichlet and Newmann conditions at the fixed face, involving Caputo fractional space derivatives of order $0<\alpha <1$. We recover the solution for the classical one-phase Stefan problem when the order of the Caputo derivatives approaches one.
