The paper presents experimental studies of nanoparticle layer, which is established on the heated surface during the boiling of nanofluid, and the influence of the process and resulting nanoparticle layer on the magnitude of critical heat flux. The examined nanofluid is distilled water (distillate) with dispersed ZrO$_2$ nanoparticles. A nichrome wire is used as heater. The varied parameters are: volumetric concentration of particles (C$_0$); exposition time in the nucleate boiling regime ($\tau$); initial heat flux at exposition ( $q_0$). Critical heat flux (CHF) was measured in each case. The morphology of nanoparticle layer produced in different conditions is analyzed using the method of scanning electron microscopy. The experiments have determined the influence of boiling parameters on the nanoparticle layer formation on the heated surface and sensitivity of the CHF magnitude to the properties of established nanoparticle layer in the experimental conditions.
Keywords: nanofluid, nanostructured surface, departure from nucleate boiling (DNB), critical heat flux (CHF).
