Bubble dynamics at boiling incipience in subcooled upward flow boiling

International Journal of Heat and Mass Transfer, 2012
Abstract Bubble dynamics in water subcooled flow boiling was investigated through visualization using a high-speed camera. The test section was a vertical rectangular channel, and a copper surface of low contact angle was used as a heated surface. Main experimental parameters were the pressure, mass flux and liquid subcooling.

Numerical investigation of subcooled flow boiling of a nanofluid

International Journal of Thermal Sciences, 2013
Abstract Subcooled flow boiling of a nanofluid consisting of water and Al2O3 (dp = 30 nm) has been investigated numerically using two phase mixture model. Numerical predictions are compared to the previously published experimental works for pure water and alumina nanofluid and a good agreement is realized.

Subcooled Flow Boiling in a Minichannel

Heat Transfer Engineering, 2009
It has been considered that the dry-out is easy to occur in boiling heat transfer for a small channel, a mini or microchannel because the channel was easily filled with coalescing vapor bubbles. In the present study, the experiments of subcooled flow boiling of water were performed under atmospheric condition for a horizontal rectangular channel of ...

Transportphenomena in subcooled flow boiling

Heat and Mass Transfer, 2010
Subcooled boiling has been subject of extensive research studies in the literature. So far, the approach of studying the phenomena of subcooled boiling has rather been an integral method by measuring the heat transport from the wall to the liquid and by following the growth and collapse of the bubbles.

A correlation to predict chf in subcooled flow boiling

International Communications in Heat and Mass Transfer, 1995
The present paper provides a discussion of the thermal-hydraulics requirements in fusion reactor components, with particular reference to the removal of high heat flux from plasma facing components and the critical heat flux (CHF) limit. Available experimental data on CHF of subcooled flow boiling in water, in the ranges of interest of fusion reactors ...

Bubble characteristics in subcooled flow boiling of seawater

Chemical Engineering Journal, 2022
Abstract Bubble characteristics are important to the two-phase flow dynamics and two-phase flow simulation. Different from the known slug flow in subcooled flow boiling of de-ionized water, fined bubbly flow and foam flow are found to be dominant in that of artificial seawater at high temperatures.

The influence of flow development on subcooled boiling

International Communications in Heat and Mass Transfer, 1990
Abstract The effect of flow development on the onset of subcooled boiling has been analyzed. It has been found that the onset of subcooled boiling is suppressed near the inlet of the channel where the flow is not thermally developed. The well-known Saha-Zuber model for the onset of subcooled boiling has been modified to accommodate flows near the ...
