Supercooled Stefan problem with a Neumann type boundary condition. <i>Electronic Journal of Differential Equations, 2020</i>(49), pp. 1-14.1072-6691https://hdl.handle.net/10877/14556We consider a supercooled one-dimensional Stefan problem with a Neumann boundary condition and a variable thermal diffusivity. We establish a necessary and sufficient condition for the heat flux at the fixed face x=0, in order to obtain existence and uniqueness of a similarity type solution. Moreover we over-specified the fixed face x=0 by a Dirichlet boundary condition aiming at the simultaneous determination of one or two thermal coefficients.Text14 pages1 file (.pdf)enAttribution 4.0 InternationalStefan problemSupercoolingNon-linear thermal diffusivitySimilarity solutionDetermination of thermal coefficientArticle
