Flow Boiling Heat Transfer Mechanism in Minichannels
ASME 5th International Conference on Nanochannels, Microchannels, and Minichannels, 2007The present study is aimed at consideration of forced boiling heat transfer in a channel whose width is comparable and less than the capillary constant. When boiling occurs inside very small and non-circular passages the constrain phenomena become important in determining the aspects of flow phenomena such as the flow pattern and microscale heat ...

Flow Boiling of Refrigerants Inside a Single Circular Minichannel
ASME 2008 6th International Conference on Nanochannels, Microchannels, and Minichannels, 2008The present paper reports the heat transfer coefficients measured during flow boiling of HFC-32 and HFC-134a in a 0.96 mm diameter single circular channel. The test runs have been performed during vaporization at around 30°C saturation temperature, correspondent to 19.3 bar for R32 and 7.7 bar for R134a.

Minichannels in Polymer Electrolyte Membrane Fuel Cells
ASME 2nd International Conference on Microchannels and Minichannels, 2004This paper provides an overview of the application of minichannels, typically on the order of 1 mm hydraulic diameter, in the design of polymer electrolyte membrane (PEM) fuel cells. In these electrochemical devices, minichannels deliver reactant hydrogen and oxygen to the anode and cathode electrodes, respectively, while transporting product water out

Predictive models for flow boiling in minichannels
2005More and more attention is being paid to the study of two-phase flow and boiling heat transfer in minichannels in the recent years. Boiling in minichannels is common application in compact heat exchangers, which are largely used in the emerging technologies, such as cooling of electronic components.
