ナノ構造物が界面エネルギ伝達へ与える影響 : 分子動力学解析(J11-1 量子・分子熱流体工学(1),J11 量子・分子熱流体工学)

Abstract

Energy transfer from fluid to the surface was calculated by using the classical molecular dynamics method in order to investigate effects of surface structures in nanometer scale on the surface energy transfer numerically. Surface structures on the constant surface area were composed of several hundred atoms having the same thermal properties. Upper region in the, calculation domain was controlled at a constant temperature and the solid atomic layer at lower region was controlled at a constant temperature so as to, make a temperature gradient in the calculation system. Fluid molecular diffusion in the vicinity of the surface was dependent on the surface structures in nanometer scale that affected the dynamic behaviors of fluid molecules in the vicinity of the surface.
