Abstract

The thermal charging performance of compressed expanded natural graphite foam saturated with a phase change material is modeled under constant heat flux and constant temperature conditions. This phase change moving boundary problem is solved with the effective heat capacity method. The graphite composite properties are modeled using empirically determined volume-averaged density, specific heat, latent heat, and thermal conductivity measurements for each composite. After being experimentally validated for constant temperature boundary conditions of 60°C and constant flux boundary conditions of 0.39 W/cm², 1.22 W/cm², and 1.55 W/cm² for graphite bulk densities of 23, 50, 100, 143 kg/m³, the use of this model is demonstrated in the design of a thermal battery. The objectives of minimizing size and refrigerant charge while maximizing heat capacity and thermal charging rate are studied as a function of the parameters graphite bulk density, thermal battery dimensions, and refrigerant tube configuration.
