Molecular simulation of the microregion.
Proceedings 2nd GASMEMS Workshop.

Abstract
When evaporation occurs in a microchannel, the most heat transfer takes place in the microregion, the region where the evaporation meniscus is in contact with the channel wall. This microregion has been studied with continuum methods before. Experimental results have shown the existence of this microregion, but, because of the small scales, its internal structure can not be verified experimentally. Here, the Molecular Dynamics technique is used to simulate the microregion, where the boundary conditions are taken directly from the continuum results. Molecular Dynamics is able to simulate on this small length scale, and the results show that, although the interface temperature differs from the continuum prediction, the results for the liquid profile and the heat transfer through the wall agree to the predictions from the continuum model.
