Temperature and Heat Flux Dependence of Interfacial Thermal Resistance for Water Between Platinum, Palladium, Lead and Nickel Nanochannel Walls
MM Aksoy and Y Bayazitoglu, INTERNATIONAL JOURNAL OF THERMOPHYSICS, 43, 128 (2022).
The reversed non-equilibrium molecular dynamics method is used to determine the interfacial thermal resistance (ITR) between liquid water and two parallel nanochannel walls. The walls are made of four different transient metals (Platinum, Palladium, Lead, and Nickel). The mean temperature of water between walls is kept constant. Different runs are made where the mean temperature for each simulation is changed from 300 K to 600 K with increments of 50 K. The temperature differences and the heat flux at the intersections of water and the walls are evaluated using numerical simulations and the ITR values are calculated. It is shown that the ITR value increases with the temperature increase, and decreases with the heat flux increase.
