EFFECTS OF HEATER-SIDE FACTORS ON THE SATURATED POOL BOILING CRITICALHEAT-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 s uspended, vertically oriented, ribbon heaters in FC-72 fluid was measu red. On the basis of comprehensive experimental results (50 data sets) and data sets available in the literature, the effects of ribbon ther mal properties and thickness were determinated. A practical criterion is proposed for sizing noninsulated ribbon heaters without significant conductance/capacitance effects. (C) Elsevier Science Inc., 1997.
