Notes

  1. 1.

    Monograph Appendix 2 gives a detailed analysis of Joule-heating phenomena.

  2. 2.

    Such forces can occur from viscous, surrounding, interstitial fluid.

  3. 3.

    \(I\!K_{ij}\) can be approximated by an average interfacial value of the \(i-j\) pair, \(I\!K_{ij}\approx \frac{I\!K_i+I\!K_j}{2}\). If the materials are the same, this collapses to simply \(I\!K\). As for the mechanical contact, \(A^c_{ij}\) is the contact area associated with the particle pair (ij).

  4. 4.

    The transverse dimensions of the box were set to be approximately unity, initially. All system parameters can be scaled to describe any specific system of interest.
