1432 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  [in Japanese] Molecular dynamics study on effects of nanoscale structure on energy transfer from fluid to surface  [in Japanese]

Energy transfer from fluid to surface was calculated by using the classical molecular dynamics method in order to investigate effects of surface structures from 0.1nm to 10nm on surface energy transfer numerically. Surface structures on a 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 a solid atomic layer at lower region was controlled at a constant temperature so as to make a temperature gradient in the calculation system. Energy transfer to the surface was much dependent on surface structures in nanometer scale that affected the effective superficial area and dynamic behaviors of fluid molecules in the vicinity of the surface.
