Effects of two-phase flow friction factor correlations on the optimal pressure drop-martinelli parameter pair in a mini-channel [PDF]
, 2014 Substantial research has been completed with more on-going on the flow pattern and heat transfer associated with two-phase flows. Discrepancies reported may have been as much as agreements, due to the different models, approaches, flow regimes ...

Heat transfer in minichannels and microchannels CPU cooling systems [PDF]
SPIE Proceedings, 2009 A CPU functioning is extremely complex and it was experimentally revealed that a direct dependence between working speed and cooling degree exists. When the contact between two surfaces is imperfect, the specific thermal resistance of interface layer suddenly increases, so it became of frequent use to apply diverse materials between the CPU and ...

Comparison of heat transfer in straight and corrugated minichannels with two-phase flow
EPJ Web of Conferences, 2014 Measurements of heat transfer rates performed with an experimental condensation heat exchanger are reported for a corrugated minichannel tube and for a straight minichannel tube. The two cases were compared at same flow regimes.

Quench front progression in a superheated porous medium: experimental analysis and model development [PDF]
, 2011 In case of severe accident in a nuclear reactor, the fuel rods may be highly damaged and oxidized and finally collapse to form a debris bed. Removal of decay heat from a debris bed is a challenging issue because of the difficulty for water to flow inside.

Saturated flow boiling in small- to micro- diameter metallic tubes: Experimental results and modeling [PDF]
, 2008 Some results of a long-term study of flow boiling patterns, heat transfer rates and pressure drop of R134a at pressures of 6-14 bar in five vertical stainless steel tubes of internal diameter 4.26, 2.88, 2.01, 1.1 and 0.52 mm are presented in this paper.
