Effects of heater-side factors on the saturated pool boiling critical heat flux

There are many aspects of critical heat flux (CHF) that still require clarification. Particularly important is the role that the heater-side factors play in CHF. The saturated pool boiling CHF on horizontally suspended, vertically oriented, ribbon heaters in FC-72 fluid was measured. On the basis of...

Description
Summary:There are many aspects of critical heat flux (CHF) that still require clarification. Particularly important is the role that the heater-side factors play in CHF. The saturated pool boiling CHF on horizontally suspended, vertically oriented, ribbon heaters in FC-72 fluid was measured. On the basis of comprehensive experimental results (50 data sets) and data sets available in the literature, the effects of ribbon thermal properties and thickness were determined. A practical criterion is proposed for sizing noninsulated ribbon heaters without significant conductance/capacitance effects.
