Surface wettability change during pool boiling of nanofluids and its effect on critical heat flux
TL;DR: In this paper, the authors studied the pool boiling characteristics of dilute dispersions of alumina, zirconia and silica nanoparticles in water and found that a significant enhancement in critical heat flux (CHF) can be achieved at modest nanoparticle concentrations (< 0.1% by volume).

Nanowires for enhanced boiling heat transfer.
Renkun Chen,Ming-Chang Lu,Vinod Srinivasan,Zhijie Wang,Hyung Hee Cho,Arun Majumdar,Arun Majumdar +6 more
TL;DR: The high surface tension forces offered by liquids in nanowire arrays made of Si and Cu can be exploited to increase both the critical heat flux (CHF) and the heat transfer coefficient (HTC) by more than 100%.
Journal ArticleDOI
Structured surfaces for enhanced pool boiling heat transfer
TL;DR: In this paper, surface roughness-augmented wettability on critical heat flux (CHF) during pool boiling with horizontally oriented surfaces was investigated, and an analytical force-balance model was extended to explain the CHF enhancement.
Journal ArticleDOI
A study of nucleate boiling heat transfer on hydrophilic, hydrophobic and heterogeneous wetting surfaces
TL;DR: In this paper, the authors focused on nucleate pool boiling under different wetting conditions, in the absence of micro-scale roughness, which is coupled with wetting phenomena.
Journal ArticleDOI
Critical heat flux maxima during boiling crisis on textured surfaces
TL;DR: A coupled thermal-hydraulic model is developed that relatesCHF enhancement to rewetting of a hot dry spot on the boiling surface, thereby revealing the mechanism governing the hitherto unknown CHF enhancement maxima.

Hydrodynamic Aspects of Boiling Heat Transfer
TL;DR: In this paper, the critical heat flux and the minimum heat flux are derived from these hydrodynamic limits, and results of investigations of nucleate boilin g are discussed and the theory of bubble growth is extended to include the effect of nonuniform temperature fields.

Effect of Surface Wettability on Active Nucleation Site Density During Pool Boiling of Water on a Vertical Surface
C. H. Wang,Vijay K. Dhir +1 more
TL;DR: In this article, the cumulative number density of the cavities and their shapes were determined with an optical microscope and the surface had a mirror finish and had a surface Ra (centerline average) value of less than 0.02 μm.
Journal Article
On the stability of boiling heat transfer
TL;DR: In this article, the authors derived the maximum and minimum heat-transfer rates in the nucleate and the film-boiling regimes, respectively, using the classical results of Helmholtz Kelvan and Rayleigh expressions.
