This page shows visualizations of water flow through a graphene nanochannel to simulate the behaviors of convection.
Convection heat transfer is assessed for a laminar flow of liquid water through single layer graphene (SLG) nanochannels of two different size configurations. Microscopic interfacial behaviours, such as velocity and temperature jump at the solid-liquid interface, become dominant at smaller scales and have been suggested to influence the convective heat transfer process. In an effort to better understand these behaviours and their effect on convection, water flow through a graphene nanochannel at constant temperature is analysed to more accurately comprehend these underlying mechanisms. The effects of channel size, velocity, and temperature jump at the interface on the resulting forced laminar convection heat transfer between SLG and water are taken into account. It is shown that the Nusselt number is considerably smaller than that at macroscale for both size configurations, and a decrease in channel dimensions exhibit a weak effect on the resulting convective heat transfer.
