“…In order to isolate the contact resistance along the bottom and top plates, tests for each composition of mixture were run for bed heights of 25 mm and 44 mm. The final ETC value was obtained by the intercept procedure described elsewhere (Halliday et al, 1996).…”

A comprehensive, unified approach, using the Linear Packing Theory and Unit Cell Model, is proposed for calculating of the effective thermal conductivity of polydispersed packed beds. In this new approach, the effect of packing density is incorporated by the use of (i) an initial porosity to take into account the packing of mono‐sized particles, and (ii) the packing size ratio as a measure of the particle‐particle interaction. The proposed approach was validated with the experimental measurements of binary and ternary beds. This new approach demonstrates that the effective thermal conductivity of beds composed of polydispersed particles can be simulated for any composition without the need to measure the in situ porosity.

This paper presents a computationally fast methodology for the estimation of spatial and transient unknown thermal contact conductance between sandwiched materials, using non-intrusive measurements. The methodology is formulated in such a way that the spatial and temporal variations of the unknown function are obtained simply by solving a linear system, whose solution vector is composed of integrals containing measured temperatures and known heat fluxes applied at an external boundary. Good estimates are obtained, even for functions containing discontinuities in both time and space. Simulated measurements with and without errors are considered, showing very good results.

“…The medium is modelled as a bi-layer composite. In these structures, the thermal contact resistance between the grains and copper affects heat transfer from one layer to the other [9][10][11][12][13][14][15][16][17]. Its value depends on the thermophysical properties and on the contact pressure.…”
