Experimental pool boiling heat transfer performance analysis on novel two-stage hybrid aligned copper oxide nanowires that stand independently and one over the other (nanowires on nanowires) surfaces

Abstract

Pool boiling capability was examined in relation to the function of copper oxide metal nanowires with varying height/density ratios. Employing a purposefully designed array of two-stage linked copper oxide nanowires, we anticipate improving liquid transport abilities and achieving significant progress towards our aim of improving critical heat flux (CHF) and heat transfer coefficient (HTC). In order to create highly dense nanostructures with continuous pitching and structure, we create two-stage oriented copper oxide nanowires which exist autonomously and one on top of the other. The fluidic resistivity caused by separate and thin grids of structures can be minimised by a hybrid unique two-stage configuration. Wicking width on hybrid nanowires is therefore regulated at the same time. It was found that boiling incipience superheat decreased, which is crucial for electronics devices. It was discovered that there was a rise in the HTC (up to 423.82 %) and the CHF (up to 105 %). The total amount of nanowires for each surface area grows as the density of nanowires rises. In favourable to pool boiling improvement, this raises both the density and dimensions of micron to nanoscale cavities. It further delays surface dryout and CHF by lowering liquid flow barrier at higher heat flux levels.
