Surface Nanobubbles Nucleate Liquid Boiling

Langmuir, 2018
Surface nanobubbles have been presumed to lead to the experimental observation that liquid boiling often occurs at a much lower supersaturation than expected, yet no qualitative theory exists to explain how they participate in the process. Here, we report through a simple theoretical analysis on how the metastable nanobubbles nucleate the liquid-to ...

Investigation of Nucleate Pool Boiling of Saturated Pure Liquids and Ethanol-Water Mixtures on Smooth and Laser-Textured Surfaces

Nanoscale and Microscale Thermophysical Engineering, 2020
Nucleate pool boiling experiments were performed on plain and five laser-textured stainless-steel foils using saturated pure water, 100% ethanol, 0.4% and 4.2% mole fraction ethanol – water mixtures. All laser-textured samples contained untreated, smooth

Jet impingement nucleate boiling

International Journal of Heat and Mass Transfer, 1986
Abstract The characterististics of nucleate boiling with jet impingement were investigated. Included are the effects of velocity, subcooling, flow direction and surface condition on fully developed boiling and on the correspondence of the extrapolation of pool boiling with developed jet boiling. Incipient boiling and partial boiling are in accordance

Experimental and semi-analytical investigation of heat transfer in nucleate pool boiling by considering surface structuring methods

, 2020
Pool boiling is the process in which the heating surface is submerged in a large body of stagnant liquid. In the present work, heat transfer in nucleate pool boiling is modeled both experimentally and semi-analytically with the consideration of surface ...

Onset of Nucleate Boiling and Active Nucleation Site Density During Subcooled Flow Boiling

Journal of Heat Transfer, 2002
The partitioning of the heat flux supplied at the wall is one of the key issues that needs to be resolved if one is to model subcooled flow boiling accurately. The first step in studying wall heat flux partitioning is to account for the various heat transfer mechanisms involved and to know the location at which the onset of nucleate boiling (ONB ...

Suppression of Flow Boiling Nucleation

Journal of Heat Transfer, 1997
A simple model is presented for estimating the ratio of the maximum to minimum cavity radius required for ebullition in two-phase flow with heat transfer. The resulting dimensionless parameter, rmax/rmin, is demonstrated to correlate flow boiling nucleation site density.
