摘要

The critical heat flux (CHF) enhancements were achieved in FC-72 pool boiling using high thermal conductive graphene layer and silicon carbide (SiC) nanoparticles deposition on ITO heaters. The values of CHF for the graphene layer on the ITO surface and SiC deposited on the ITO heater were increased by 9% and 42%, compared to the bare ITO heater, respectively. Infrared (IR) thermometry was used to acquire boiling curves. The enhancement mechanisms were investigated in terms of high thermal conductivity and porosity characterizing the surface modifications based on graphene and SiC, respectively.
