abstract = {I study the heat transfer in systems of weakly interacting
particles at low confining pressure in the normal
atmosphere. The particles have surface roughness with
self-affine fractal properties, as expected for mineral
particles produced by fracture, e.g., by crunching brittle
materials in a mortar. I show that for small particles (say
<10 μm) with hydrophilic surfaces, at large humidity water
capillary bridges dominate the heat transfer, while for big
particles heat transfer via the air dominates. This differs
from vacuum conditions where the propagating electromagnetic
(EM) waves give the dominant heat transfer for large
particles, while for small particles both the evanescent
EM-waves and the phononic contribution from the area of real
contact are most important.},
