(192az) Effect of Liquid-Liquid and Solid-Liquid Interfacial Resistance on Heat Transfer in Nanomaterials

We have used molecular dynamics simulations to demonstrate that significant role of solid-fluid and liquid-liquid interfaces on thermal transport in nano-devices. By manipulating solid-fluid and liquid-liquid interfaces between a thin solid wall and a liquid and two immiscible liquids we have also demonstrated the possibility of rectification as well as the direction of rectification. This thus opens the possibilities of more precise control of heat transfer rates. Our simulations also show that interface manipulations of the type introduced here can lead to over six fold increase in heat transfer rates in nano-devices. Dissipating heat from miniaturized semi-conductors of the future will become increasingly challenging since size limitations are often dictated by the heat dissipation rates.
