Heat conduction across a solid-solid interface: Understanding nanoscale interfacial effects on thermal resistance

Unsteady nanoscale thermal transport across a solid-fluid interface

Thermal Contact Resistance at a Metal Foam-solid Surface Interface

Accurate information on heat transfer and temperature distribution in metal foams is necessary for design and modeling of thermal-hydraulic systems incorporating metal foams. The analysis of this process requires determination of the effective thermal conductivity as well as the thermal contact resistance (TCR) associated with the interface between the metal foams and adjacent surfaces/layers. ...

Solid–solid transformations via nanoscale intermediate interfacial phase: Multiple structures, scale and mechanics effects

Solid–solid ðSSÞ phase transformations via nanometer-size intermediate melts ðIMsÞ within the SS interface, hundreds of degrees below melting temperature, were predicted thermodynamically and are consistent with experiments for various materials. A necessary condition for the appearance of IMs, using a sharp interface approach, was that the ratio of the energies of SS and solid–melt ðSMÞ interf...

Heat conduction through a trapped solid: effect of struc- tural changes on thermal conductance

– We study the conduction of heat across a narrow solid strip trapped by an external potential and in contact with its own liquid. It is possible to produce structural changes in the trapped solid by altering the depth of the confining potential. We find, using nonequilibrium molecular dynamics simulations, supported wherever possible by simple analytical calculations, the thermal resistance in...

Heat Conduction in Fine Scale Mixtures With Interfacial Contact Resistance

Heat conduction in a ne scale mixture of two conductors is examined in the presence of a contact resistance between phases. The problem is studied rigorously in the context of periodic homogenization. Unlike the case of perfect heat transmission between phases, the temperature elds studied here may converge weakly in L to the homogenized temperature. The temperature gradients converge weakly as...
