Effective Thermal Conductance of Frost

  • C. J. Cremers

A model for the effective local thermal conductance of frost is developed that includes both sensible and latent heat effects. The model contains several constants that are evaluated from data of Shah given in the literature. The results are shown as a function of density with local temperature as the parameter. Then, an average affective thermal conductance for the Shah experiment is obtained by integrating the local conductance over the range of temperatures in his experiment. This prediction is subsequently compared with several sets of data from the literature.
