A predictive model for confined and unconfined nucleate boiling heat transfer coefficient
(2017-01-01)
The aim of this study is to investigate the influences of different parameters on the boiling phenomenon. In this paper, a new correlation to predict the pool boiling heat transfer coefficient is presented. The developed ...
Modeling and experimental study of nucleate boiling on a vertical array of horizontal plain tubes
(ELSEVIER SCIENCE INC, 2008)
An investigation of nucleate boiling on a vertical array of horizontal plain tubes is presented in this paper. Experiments were performed with refrigerant RI 23 at reduced pressures varying from 0.022 to 0.64, tube pitch ...
Confined and unconfined nucleate boiling of HFE7100 in the presence of nanostructured surfaces
(2018-02-01)
This article presents experimental results for the confined and unconfined nucleate boiling of saturated HFE7100 (C4F9OCH3) at atmospheric pressure and using nanostructured copper discs as heating surfaces. The nanostructures ...
Roughness and surface material effects on nucleate boiling heat transfer from cylindrical surfaces to refrigerants R-134a and R-123
(ELSEVIER SCIENCE INC, 2009)
This paper presents results of an experimental investigation carried out to determine the effects of the surface roughness of different materials on nucleate boiling heat transfer of refrigerants R-134a and R-123. Experiments ...
Experimental investigation of wall nucleation characteristics in flow boiling
(American Society of Mechanical Engineers, 2015-05)
Wall nucleation experiments have been performed in a vertical annulus test section for investigation of the bubble departure diameter and bubble departure frequency. The experimental data in forced convective subcooled ...
Influence of nanoparticle size and gap size on nucleate boiling using HFE7100
(Elsevier B.V., 2014-11-01)
In this study the effect of the deposition of maghemite (gamma-Fe2O3) nanoparticles on a horizontal heated copper surface during the nucleate boiling of HFE7100, at atmospheric pressure and saturation temperature, was ...
