摘要

Motion of a nanoscale droplet on a solid wall with temperature gradient was numerically simulated by using the molecular dynamics method. Two types of droplet configuration were considered: semi-cylindrical and hemispherical droplets. The numerical results showed the droplet motion directed to the lower temperature side, and the velocity was larger for the stronger interaction case between the fluid and solid molecules, that is, the higher wettability and the lower contact angle case. The larger size of the droplet gave the lower velocity, and the velocity of the hemispherical droplet was lower than that of the semi-cylindrical droplet.
