A new technical paper titled “Thermal Slip Length at a Liquid/Solid Interface: Power Law Relations From Spatial and Frequency Attributes of the Contact Layer” was published by researchers at California Institute of Technology, , T. J. Watson Sr. Laboratories of Applied Physics.
Abstract
“Specialty integrated chips for power intensive tasks like artificial intelligence generate so much heat that data centers are switching to liquid cooling to prevent malfunction. A critical factor hindering optimization of the thermal flux across the liquid/solid (L/S) interface is the lack of any predictive model for the thermal slip length at non-cryogenic temperatures. An extensive study using non-equilibrium molecular dynamics simulations reveals distinct power law relations governing this length scale which incorporate the influence of local temperature, in-plane translational order and vibrational frequency of the liquid contact layer and adjoining solid layer. Similar relations are expected to hold for other L/S systems modeled by the Lennard-Jones potential given the principle of corresponding states.”
