Critical outflow for a steady-state stefan problem
The problem of the steady temperature distribution in a container of fluid that is kept at a given positive temperature over a part of its boundary and is cooled with a given rate q on the rest of the boundary is considered. It is shown that there exists a critical qc >0 such that for q &...

| Sumario: | The problem of the steady temperature distribution in a container of fluid that is kept at a given positive temperature over a part of its boundary and is cooled with a given rate q on the rest of the boundary is considered. It is shown that there exists a critical qc >0 such that for q > qc the temperature is negative in a part of the fluid and this is interpreted as the existence of a solid phase together with the liquid fase. For q < qc the temperature is positive and there is only liquid in the container. Various estimates for qc are given in terms of the geometry. © 1989, Taylor & Francis Group, LLC.
