MICHAEL MANGA: Recent Refereed Publications
Li, X., M. Manga, J.N. Nguyen and R. Jeanloz (1996) Temperature profile in a
laser-heated diamond cell with external heating, and implications
for the thermal conductivity of (Mg,Fe)SiO3 perovskite,
Geophysical Research Letters, vol. 23, 3775-3778.
Applying external heating reduces temperature gradients in
the laser-heated diamond cell by roughly a factor of two
as the external temperature is raised by 300 K.
A heat conduction model is presented
which can account for most of the reduction.
In addition, the temperature
distribution measured in a (Mg0.86Fe0.14)SiO3
perovskite sample at 56 GPa is compatible the
expected inverse temperature-dependence of thermal conductivity.
