Pool Boiling of Micro-/Nanoparticles Modified Aluminum Surface

Pool boiling of nanoparticle-modified surface with interlaced wettability

This study investigated the pool boiling heat transfer under heating surfaces with various interlaced wettability. Nano-silica particles were used as the coating element to vary the interlaced wettability of the surface. The experimental results revealed that when the wettability of a surface is uniform, the critical heat flux increases with the more wettable surface; however, when the wettabil...

Nucleation Site Density in Pool Boiling of Binary Mixtures: Effect of Surface Micro-roughness and Surface and Liquid

The nucleation site density (N/A) during pool boiling of binary mixtures has been experimentally examined in terms of the heating surface physical properties, the liquid physical properties, the vapour liquid equilibria and the surface micro-roughness. The liquid mixtures used were acetone carbon tetrachloride and n-hexane carbon tetrachloride. A parameter R,, to characterize the micro-roughnes...

Secondary pool boiling effects

Transient pool boiling in microgravityt

Transient nucleate pool boiling experiments using R113 are conducted for short times in microgravity and in earth gravity with different heater surface orientations and subcoolings. The heating surface is a transparent gold film sputtered on a quartz substrate, which simultaneously provides surface temperature measurements and permits viewing of the boiling process from beneath. For the microgr...

Pool Boiling Heat Transfer in Water/Amines Solutions

In this investigation, nucleate boiling heat transfer coefficients were experimentally measured during pool boiling of mixtures, consisting of water/monoethanolamine and water/diethanolamine on a horizontal heating rod, under atmospheric pressure. The experiment was carried out below 205 kW.m-2 heat flux, over a wide range of concentrations. These experiments include, measurement of pool boilin...
