Thermal mutual inductance: http://www.nature.com/nature/journal/v161/n4083/abs/161166a0.html Thermal inductance: http://adsabs.harvard.edu/full/1963AuJPh..16..353B The term thermal inductnace also occurs in Tokamak literature as well as in the the application of Josephson Junctions. However the meaning differs from the convection case.
