The conduction along the radial direction of CuNW-SWCNT nanocomposite surrounded with water is examined. Due to its simplicity and adaptability, a simple point-charge water model is implemented. Using the Nose-Hoover thermostat, the copper core is kept at a uniform temperature as a heat source, and a circular edge layer of water is kept at a lower temperature as a heat sink in order to impose a radial temperature distribution. The thermal boundary resistance was predicted as 0.1732 x 10(8) m(2) K/W at the interface of CuNW-water, 3.16 x 10(-8) m(2) K/W at the interface of SWCNT-water, and 0.743 x 10(-8) m(2) K/W at the interface of (CuNW-SWCNT)-water.
