In this paper, we present the experimental investigation of pool boiling heat transfer on
multiscale (micro/nano) functionalized metallic surfaces. The multiscale structures were
fabricated via a femtosecond laser surface process (FLSP) technique which forms mound-
like microstructures covered by layers of nanoparticles. Using a pool boiling experimental
setup with deionized water as the working fluid, both the heat transfer coefficient and critical
heat flux were investigated. The polished reference sample was found to have a critical heat …

In this paper, we present an experimental investigation of pool boiling heat transfer on
multiscale (micro/nano) functionalized metallic surfaces. Heat transfer enhancement in
metallic surfaces is very important for large scale high heat flux applications like in the
nuclear power industry. The multiscale structures were fabricated via a femtosecond laser
surface process (FLSP) technique, which forms self-organized mound-like microstructures
covered by layers of nanoparticles. Using a pool boiling experimental setup with deionized …
