Analytical modeling of a hydride heat exchanger

In order to obtain some of the parametric features of the problem of conduction in a hydride bed, a computer program was developed. For simplicity a one-dimensional slab with constant temperature boundary conditions was considered. The phase change corresponding to the adsorption/desorption of hydrogen was modeled as a sharp increase in specific heat at the phase change temperature. All other thermal properties were assumed to be constant with temperature. The computer program was used to solve a number of cases with the results put into dimensionless form. The results of these runs, and the conclusion to be drawn are discussed.
