Molecular Dynamics Method for Microscale Heat Transfer

Molecular dynamics methods in microscale heat transfer

In normal heat transfer and fluid flow calculations, the fluid phases are treated as being continuous with properties such as viscosity and thermal conductivity being assumed to be only a function of local pressure, composition and temperature in the flow domain. However, as the size of the flow domain (the channel) becomes smaller and smaller, the continuum treatment breaks down since, in real...

The Effect of Thermal Accommodation on Unsteady Microscale Heat Transfer

Thermal accommodation coefficient, one of the fundamental parameters in rarefied gas dynamics, is usually introduced to account for the fraction of incident molecules interacting with solid surface in a diffusive manner. In the present study, the effects of thermal accommodation on the unsteady one-dimensional micro-flow are examined, when the oscillating flow input is applied, by employing the...
