Correlations for nucleate boiling heat transfer should be improved, or in the long term possibly be replaced, by the development of mechanistic simulations that include the non-uniform spacing and variable characteristics of the nucleation sites and

Saturated flow boiling of water in a narrow channel: time-averaged heat transfer coefficients and correlations

Autor: Y. Yan, Dongsheng Wen, D.B.R. Kenning

Publikováno v: Applied Thermal Engineering. 24:1207-1223

Time-averaged local heat transfer coefficients were measured during flow boiling of water at atmospheric pressure in a vertical channel of rectangular cross-section 2 mm by 1 mm for ranges of mass flux 57–211 kg/m2 s, heat flux 27–160 kW/m2, ther

Optical studies of boiling heat transfer: insights and limitations

Autor: D.B.R. Kenning

Publikováno v: International Journal of Heat and Fluid Flow. 25:209-222

Optical studies provide valuable insights into the complex mechanisms of boiling heat transfer but the large gradients of temperature (and therefore of refractive index) deflect light and multiple reflections at interfaces limit the distance over whi

Two-phase pressure drop of water during flow boiling in a vertical narrow channel

Autor: Dongsheng Wen, D.B.R. Kenning

Publikováno v: Experimental Thermal and Fluid Science. 28:131-138

Two-phase pressure drop during flow boiling of water in a vertical channel with cross-section 2 mm by 1 mm was investigated experimentally. The experiments were performed for the conditions of heat flux from 25 to 105 kW/m2, mass flux from 57 to 211

Examination of the Mass–Heat Transfer Analogy for Two-Phase Flows in Narrow Channels

Autor: Zhanfeng Cui, S.R. Smith, D.B.R. Kenning, Dongsheng Wen, Taha Taha

Publikováno v: Chemical Engineering Research and Design. 80:729-738

The analogy between heat and mass transfer is frequently employed in single-phase flows. Here the analogy is examined for two processes involving two-phase flow in meso-channels with bores ≤1 mm: the injection of gas bubbles to enhance the ultrafil

Saturated Flow Boiling of Water in a Narrow Channel: Experimental Investigation of Local Phenomena

Autor: Y. Yan, D.B.R. Kenning

Publikováno v: Chemical Engineering Research and Design. 79:425-436

This paper describes some observations of flow boiling of water at near-atmospheric pressure in a single vertical channel of rectangular cross-section 2 mm × l mm, heated on three sides over a length of 248 mm, with a window on the fourth side. Meas

Sliding and sticking vapour bubbles under inclined plane and curved surfaces

Autor: D.B.R. Kenning, Keith Cornwell, Y. Yan

Publikováno v: International Journal of Refrigeration. 20:583-591

In flow boiling heat is transferred by the combined effects of nucleate boiling, with local generation of bubbles, and evaporative and convective cooling by the passage of bubbles generated elsewhere. In this study, nucleate boiling was eliminated by
