Occurrence of critical heat flux during blowdown with flow reversal

The Effect of Linear Change of Tube Diameter on Subcooled Flow Boiling and Critical Heat Flux

One of the major industry problems is the flow boiling, where reaching to the critical heat flux (CHF) condition can lead to a temperature jump and damage of the systems. In the present study, the effects of a uniform change in tube diameter on subcooled flow boiling and CHF was numerically investigated. The Euler-Euler model was used to investigate the relationship between the two liquid and v...

A Study of Critical Heat Flux during Flow Boiling in Microchannel Heat Sinks

Critical Heat Flux in Subcooled Flow Boiling of Water

Effects of Orientation on Critical Heat Flux From Chip Arrays During Flow Boiling

Boiling experiments were performed with FC-72 on a series of nine in-line simulated microelectronic chips in a flow channel to ascertain the effects of channel orientation on critical heat flux (CHF). The simulated chips, measuring 10 mm x 10 mm, were flush-mounted to one wall of a 20 mm x 5 mm flow channel. The channel was rotated in increments of 45 degrees through 360 degrees such that the c...

Nucleate Boiling and Critical Heat Flux From Protruded Chip Arrays During Flow Boiling

The effects of chip protrusion on the forced-convection boiling and critical heat flux (CHF) of a dielectric coolant (FC-72) were investigated. The multi-chip module used in the present study featured a linear array of nine, 10mm x 10 mm, simulated microelectronic chips which protruded 1 mm into a 20-mm wide side of a rectangular flow channel. Experiments were performed in vertical upflow with ...
