Abstract:

The memorandum relates to the development of an analog solution of the two-dimensional transient temperature field in a continuous object undergoing a change of phase due to some prescribed temperature conditions imposed on its exposed surface. The analog solution is based on the measurements of the concentration profile obtained by molecular diffusion in a partially miscible liquid-liquid binary mixture in a diffusion cell. The diffusion analog can be used to determine movements of the interface and the temperature distribution, when the boundary of the region under consideration is not a simple geometrical surface and the boundary conditions are strongly dependent on the location and time. The use of this cell to solve several cases of practical interest, such as periodic and irregular boundary conditions, is outlined. Author
