Abstract
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 a calculation system. Volume density of fluids were changed from 0.0192g/(cm)^3 to 1.23g/(cm)^3 in the present study. Energy transfer to the surface was much dependent on surface structures in nanometer scale and surface structures in nanometer scale affected the number of fluid molecules that could exchange their kinetic and potential energy to surface atoms in the vicinity of the surface.
