On the convergence of the heat balance integral method. (English) Zbl 1151.80329
The authors apply the well-known Godmann’s approximate heat-balance method to the single-phase semi-infinite ice slab, whose exact solution is well-known and represents a special case of the Neumann general solution. The distance from the beginning of the slab $$(x= 0)$$ to the moving melt front $$(x= s)$$ is subdivided into $$n$$ equal cells and the temperature is approximated at each node by a linear temperature profile. The further calculation is performed by the Godmann method. The authors demonstrated that the approximate solution obtained in such a way, is in good agreement with the exact solution. The study of the convergence of the approximate solution is accomplished in details.
