摘要: Abstract In this study, Ag, Cu, and Al 2 O 3 nanofluids were produced from the electrical explosion of a wire in liquid (EEWL). Compared with two-step method, various manufactured by EEWL process had higher purity dispersion states. Pool-boiling experiments performed to evaluate their critical heat flux (CHF) enhancements, which 187% at 0.001 vol% for , 58% 99% Cu. The surface heating was observed using transmission electron microscopy (TEM) atomic force (AFM) after pool boiling. heater contained deposited nanoparticles that formed nano/microstructures different uniformity according state. Build-up on occurred during nucleate boiling, improved wettability. layer contributed CHF enhancement.
