Equilibrium molecular dynamics study of heat conduction in octane
Fluids are important components in heat transfer systems. Understanding heat conduction in liquids at the atomic level would allow better design of liquids with specific heat transfer properties. However, heat transfer in molecular chain liquids is a complex interplay between heat transfer within a …

Analytical and experimental studies for space boundary and geometry inverse heat conduction problems
Inverse Heat Conduction Problems (IHCPs) have been widely used in engineering fields in recent decades. IHCPs are not the same as direct heat conduction problems which are "well-posed". IHCPs are made more difficult since they are inherently "ill-posed"; that is, a small error perturbation will …

Studies of non-diffusive heat conduction through spatially periodic and time-harmonic thermal excitations
Studies of non-diffusive heat conduction provide insight into the fundamentals of heat transport in condensed matter. The mean free paths (MFPs) of phonons that are most important for conducting heat are well represented by a material's thermal conductivity accumulation function. Determining …
