dc.description.abstract | As microchannels are applied in flow boiling applications, it is
becoming apparent that the Reynolds number based on all
liquid flow could approach values below 100. The earlier work
by Kandlikar and Steinke (2002, 2003) provided modifications to
the Kandlikar correlation (1990,1991) by extending the range of
the correlation to all-liquid Reynolds numb ers in the range 1000
– 3000.
The present work utilizes the newly available data on flow
boiling in microchannels that cover the all-liquid flow Reynolds
number between 50 – 500. A new correlation is developed in this
range that is able to predict the flow boiling heat transfer
coefficient and its trends with quality, heat flux and mass flux
accurately within less than 15 percent mean deviation. It is
noted that the correlation simply accounts for the change of the
flow boiling mechanism without incorporating any additional
empirical constants. The heat transfer mechanism during flow
boiling at such low Reynolds numbers is altered considerably
indicating strong presence of nucleate boiling mode of heat
transfer. | en_US |
