THERMAL RECTIFICATION IN NANOSCALE CONFINED FLUIDS WITH NANOPATTERNED SURFACE
Abstract
By using nonequilibrium molecular dynamics (NEMD) simulations, we examine the thermal rectification in nanoscale confined fluids with nanopatterned surface. Effects of the temperature and fluid density on the thermal rectification are discussed respectively. It is shown that the rectification factor assumes a maximum value as the high temperature is varied for a fixed low temperature. Lower number density can improve the rectification factor but suppresses the heat transport.
