Saturated Critical Heat Flux in a Multi-Microchannel Heat Sink Fed by a Split Flow System [PDF]
An extensive experimental campaign has been carried out for the measurement of saturated critical heat flux in a multi-microchannel copper heat sink. The heat sink was formed by 29 parallel channels that were 199 μm wide and 756 μm deep.

Gravity independent subcooled flow boiling heat transfer regime
Abstract Using an existing model for vapor bubble detachment, a subcooled flow boiling regime was identified where vapor bubble dynamics are independent of the gravitational field. The Jakob number and a dimensionless flow parameter were used to identify the boundaries of this regime.
