摘要
We consider a nonlinear one-dimensional Stefan problem for a semi-infinite material x > 0, with phase change temperature Tf. We assume that the heat capacity and the thermal conductivity satisfy a Storm's condition, and we assume a convective boundary condition at the fixed face x = 0. A unique explicit solution of similarity type is obtained. Moreover, asymptotic behavior of the solution when h -> +infinity is studied.
